feat: implement repository clone mode with SSH key support

- Add clone_mode and branch fields to tool_instances
- Add ssh_key_id to git_repositories for per-repo SSH key assignment
- Implement host-side git cloning with branch selection (default: main)
- Mount SSH keys into containers for git operations in clone mode
- Add dirty state check on clone-mode instance deletion with confirmation
- Update SessionsPage with mount/clone selector, branch input, SSH key display
- Add SSH key selector to repository creation form
- Add dirty delete confirmation modal with changed files list
- Update API schemas and endpoints for new fields
- Sync delta specs to main specs (git-repo, tool-instances, repo-clone-mode)
- Archive completed OpenSpec change: repo-clone-mode-with-ssh
- Document git requirement for custom tool types

Quality gates: Frontend typecheck and build passed
OpenSpec: repo-clone-mode-with-ssh archived with all tasks complete

+#### Git Requirement for Clone Mode
+
+When users create instances in **clone mode** (fresh repository copy instead of bind mount), the container image must have `git` installed. This enables git operations (push, pull, branch) inside the container.
+
+**Built-in types with git:**
+- VS Code Server: Includes git
+- Jupyter Notebook: Includes git
+- OpenCode: Installs git during startup
+
+**Custom tool types:** Ensure your base image includes git (e.g., `apt-get install -y git` in Dockerfile).

+## Context
+
+Currently, all tool instances bind-mount the host repository path via `{{REPO_PATH}}` substitution in compose templates. The repository model (`GitRepository`) has no SSH key association. The instance model (`ToolInstance`) has no concept of repository access mode.
+
+Users want two modes:
+1. **Mount** (current): Live sync with working copy on host
+2. **Clone** (new): Fresh isolated copy with full git history inside the container
+
+The SSH key system already exists with encrypted private keys in the database. Keys can be project-scoped or user-scoped.
+
+## Goals / Non-Goals
+
+**Goals:**
+- Allow per-instance choice between mount and clone mode
+- Support branch selection for clone mode (default: main)
+- Enable git operations inside containers via SSH key mounting
+- Protect against accidental data loss with dirty check on clone deletion
+- Allow SSH key assignment at repository creation and later modification
+
+**Non-Goals:**
+- Modifying existing tool type compose templates
+- Installing git in containers (assumes tool images have git or install it)
+- Multiple SSH keys per container
+- Automatic push/pull/sync between host and container
+- Shallow clones (full history only)
+
+## Decisions
+
+### 1. Host-Side Clone (not in-container)
+
+**Decision**: Clone happens on the host before container start, not inside the container.
+
+**Rationale**:
+- No changes to compose templates required
+- Works with all existing tool types immediately
+- No need for git/SSH inside every container image
+- Host has direct filesystem access to the clone
+- Easier error handling and rollback
+
+**Alternative considered**: In-container clone via command override. Rejected because it requires git in every image, SSH auth setup inside containers, and makes error handling fragile.
+
+### 2. SSH Key Mounting via `_modify_compose_file`
+
+**Decision**: Inject SSH key volume dynamically at container start time using the existing `_modify_compose_file` helper.
+
+**Rationale**:
+- Zero changes to tool type definitions
+- Consistent with how other runtime overrides work (port, command, working_dir, extra_volumes)
+- Mounts the `.ssh/` directory with key + config into container
+
+**Implementation**:
+```
+instance_dir/.ssh/
+  id_ed25519      (decrypted private key, mode 600)
+  id_ed25519.pub  (public key)
+  config          (StrictHostKeyChecking no)
+```
+
+Mounted as: `instance_dir/.ssh:/root/.ssh:ro` (or appropriate home dir)
+
+### 3. Single SSH Key per Repository
+
+**Decision**: The SSH key is stored on `GitRepository` and used for both clone and container access.
+
+**Rationale**:
+- Natural association: a repository's clone URL determines which SSH key is needed
+- Simpler UX: one key per repo, not per session
+- Session creation can override (future enhancement) but defaults to repo key
+
+### 4. Dirty Check via `git status --short`
+
+**Decision**: Check for uncommitted changes using `git status --short` before allowing deletion of clone-mode instances.
+
+**Rationale**:
+- Simple and reliable
+- Catches staged, unstaged, and untracked files
+- Fast (local filesystem operation)
+
+## Risks / Trade-offs
+
+**[Risk] Disk space usage** → Each clone-mode instance duplicates the full repository. Mitigation: Instance deletion removes the clone directory.
+
+**[Risk] Clone time for large repos** → Synchronous clone during instance creation may timeout. Mitigation: No timeout on clone operation; consider async clone in future.
+
+**[Risk] SSH key permissions in containers** → Some containers run as non-root users. The `.ssh` directory mount needs correct ownership. Mitigation: Mount as read-only; container's entrypoint may need to copy to writable location if needed.
+
+**[Risk] Git not installed in custom tool images** → User-defined tool types may not have git. Mitigation: Document requirement; built-in types already have or install git.
+
+**[Risk] SSH host key checking** → Cloning from new hosts may fail. Mitigation: SSH config sets `StrictHostKeyChecking no` for clone operations.
+
+## Migration Plan
+
+1. Run Alembic migrations to add new columns
+2. Existing instances default to `clone_mode='mount'` (no behavior change)
+3. Existing repositories have `ssh_key_id=null` (no behavior change until assigned)
+4. No data migration needed
+
+## Open Questions
+
+- Should the `.ssh` mount be read-only or writable? (Writable needed if container generates new keys, but we don't support that)
+- Should we support submodules in cloned repos?

+## Why
+
+Currently all tool instances bind-mount the host repository directory, giving containers live access to the working copy. Users need the ability to launch instances with an isolated fresh clone instead — useful for experimentation, clean-room development, or running tools that modify files without affecting the host copy. Additionally, containers need SSH key access to perform git operations (push/pull) inside the clone.
+
+## What Changes
+
+- **Repository-level SSH key assignment**: Each `GitRepository` can be associated with an SSH key (used for cloning and container git access). Configurable at creation time and editable later.
+- **Clone mode for tool instances**: When creating a tool instance, users can choose between:
+  - **Mount** (default): Bind-mount the host repository directory (current behavior)
+  - **Clone**: Clone the repository into the instance directory with full history
+- **Branch selection**: When clone mode is selected, users can specify a branch (defaults to `main`).
+- **SSH key mounting**: The repository's SSH key is decrypted and mounted into the container's `~/.ssh/` directory, enabling git operations inside the container.
+- **Dirty check on delete**: When deleting a clone-mode instance, check for uncommitted changes in the cloned repository. If changes exist, warn the user and require confirmation before deletion.
+- **Frontend UI updates**: Sessions page gets a repository access mode selector (mount/clone), branch input, and SSH key selector when clone is chosen.
+- **Backend API updates**: `POST /instances` accepts `clone_mode` and `branch`; new endpoint for updating repository SSH key.
+- **Database migrations**: Add `ssh_key_id` to `git_repositories`, `clone_mode` and `branch` to `tool_instances`.
+
+## Capabilities
+
+### New Capabilities
+- `repo-clone-mode`: Repository clone mode with host-side cloning, branch selection, and SSH key mounting for container git access.
+
+### Modified Capabilities
+- `git-repo`: Add `ssh_key_id` field and API for associating SSH keys with repositories.
+- `tool-instances`: Extend instance creation to support `clone_mode` and `branch`, mount SSH keys at startup, and perform dirty check on deletion.
+
+## Impact
+
+- **Database**: Migrations for `git_repositories.ssh_key_id`, `tool_instances.clone_mode`, `tool_instances.branch`
+- **Backend API**: `POST /instances` schema change, new `PATCH /repositories/{id}/ssh-key` endpoint, instance delete logic update
+- **Frontend**: SessionsPage form additions, confirmation modal for dirty delete
+- **Docker**: Dynamic SSH key volume injection via `_modify_compose_file`
+- **Tool types**: Built-in tool images assumed to have git installed (code-server, jupyter do; opencode template already installs git)

+## ADDED Requirements
+
+### Requirement: Clone mode instance creation
+The system SHALL support creating tool instances with a clone mode that clones the repository into the instance directory.
+
+#### Scenario: Create instance in clone mode
+- **GIVEN** an authenticated user with a repository that has an SSH key and remote URL
+- **WHEN** they create an instance with `clone_mode: "clone"` and `branch: "main"`
+- **THEN** the system clones the repository into the instance directory
+- **AND** the compose file uses the clone path as `REPO_PATH`
+- **AND** the instance record stores `clone_mode="clone"` and `branch="main"`
+
+#### Scenario: Create instance in mount mode
+- **GIVEN** an authenticated user with a repository
+- **WHEN** they create an instance with `clone_mode: "mount"` (or omit the field)
+- **THEN** the compose file uses the host repository path as `REPO_PATH`
+- **AND** the instance record stores `clone_mode="mount"`
+
+### Requirement: SSH key mounting for git operations
+The system SHALL mount the repository's SSH key into clone-mode containers for git operations.
+
+#### Scenario: Start clone-mode instance
+- **GIVEN** a clone-mode instance with an associated SSH key
+- **WHEN** the instance is started
+- **THEN** the SSH key is decrypted and written to `instance_dir/.ssh/`
+- **AND** the `.ssh` directory is mounted into the container
+- **AND** the container can perform git push/pull operations
+
+### Requirement: Dirty check on clone deletion
+The system SHALL check for uncommitted changes before deleting a clone-mode instance.
+
+#### Scenario: Delete clean clone
+- **GIVEN** a clone-mode instance with no uncommitted changes
+- **WHEN** the user requests deletion
+- **THEN** the instance is deleted successfully
+
+#### Scenario: Delete dirty clone with confirmation
+- **GIVEN** a clone-mode instance with uncommitted changes
+- **WHEN** the user requests deletion
+- **THEN** the system returns a warning with change details
+- **AND** the user must confirm deletion
+
+#### Scenario: Force delete dirty clone
+- **GIVEN** a clone-mode instance with uncommitted changes
+- **WHEN** the user requests deletion with `force=true`
+- **THEN** the instance is deleted regardless of uncommitted changes
+
+## MODIFIED Requirements
+
+None.
+
+## REMOVED Requirements
+
+None.
