style: fix all ruff and eslint errors across codebase

Backend (ruff):
- Fix 106 errors: move imports to top of file (E402)
- Remove unused imports (F401)
- Add missing imports for undefined names (F821)
- Remove unused variables (F841)
- Fix test_models.py broken RefreshToken test
- Fix test_projects_api.py missing TestClient import

Frontend (eslint):
- Remove unused imports/variables across 10 files
- Fix explicit any types in client.ts and sessions.ts
- Clean up empty block statements in terminal.tsx

Quality gates: ruff (pass), eslint (pass), tsc --noEmit (pass),
pytest (98 passed, 4 pre-existing failures)

+# Config Profiles
+
+## Overview
+
+Config profiles allow users to define reusable configuration sets for tool instances. Profiles can include environment variables, files, mounts, and git repository mounts. They support profile includes for composition and can be scoped to specific projects or tool types.
+
+## Git Mounts
+
+Git mounts allow you to mount files or directories from git repositories into tool instances at startup.

+**Fields:**
+
+| Field | Type | Required | Description |
+|-------|------|----------|-------------|
+| `repo_id` | string (UUID) | Yes | ID of the git repository to mount from |
+| `source_path` | string | No | Path within the repository (default: "."). Supports glob patterns like "*.json" or "configs/**" |
+| `target_path` | string | Yes | Absolute path inside the container where files will be mounted |
+| `branch` | string | No | Branch or tag to checkout before mounting (default: current branch) |
+
+### Path Validation
+
+- `source_path`: Must be relative (no leading `/`). Cannot contain `..` (path traversal)
+- `target_path`: Must be absolute (starts with `/`). Cannot contain `..`
+
+### Glob Patterns
+
+The `source_path` supports standard glob patterns:
+
+- `*.json` - Match all JSON files in root
+- `configs/**` - Match all files in configs directory recursively
+- `src/*.py` - Match all Python files in src directory
+- `.` - Mount entire repository (default)
+
+**Limits:**
+- Maximum 100 matches per glob pattern
+- Only matches within the repository boundary
+
+### Branch Behavior
+
+When a `branch` is specified:
+
+1. System attempts to checkout the branch in the existing clone
+2. If branch doesn't exist locally, attempts to fetch from remote and checkout
+3. If checkout fails, logs warning and continues with current branch
+4. No branch specified: uses current checked-out branch
+
+**Auto-clone:** If repository is not cloned locally, the system will automatically clone it using the repository's configured SSH key.
+
+## Endpoints
+
+### List Config Profiles
+
+```
+GET /config-profiles
+```
+
+Query parameters:
+- `project_id` (optional): Filter by project compatibility
+- `tool_type_id` (optional): Filter by tool type compatibility
+
+Response includes `git_mounts` array in each profile.
+
+### Create Config Profile
+
+```
+POST /config-profiles
+```
+
+Request body:
+```json
+{
+  "name": "My Profile",
+  "git_mounts": [
+    {
+      "repo_id": "550e8400-e29b-41d4-a716-446655440000",
+      "source_path": "configs/*.json",
+      "target_path": "/app/config",
+      "branch": "main"
+    }
+  ]
+}
+```
+
+Validation:
+- All referenced repositories must exist
+- Repositories must belong to the same project (if profile has project_id)
+- source_path and target_path must pass path validation
+
+### Update Config Profile
+
+```
+PUT /config-profiles/{id}
+```
+
+Same request body as create. Partial updates supported (omit fields to keep current values).
+
+### Preview Resolved Profile
+
+```
+GET /config-profiles/{id}/preview
+```
+
+Returns the fully resolved profile with all includes merged. Git mounts from included profiles are merged with override rules (later profiles override earlier ones with same repo_id + target_path combo).
+
+Response:
+```json
+{
+  "profile_id": "550e8400-e29b-41d4-a716-446655440000",
+  "profile_name": "My Profile",
+  "env_vars": {},
+  "runtime_hints": {},
+  "mounts": [],
+  "git_mounts": [
+    {
+      "repo_id": "550e8400-e29b-41d4-a716-446655440000",
+      "source_path": "configs/*.json",
+      "target_path": "/app/config",
+      "branch": "main"
+    }
+  ],
+  "files": {},
+  "overrides": {
+    "env_vars": {},
+    "runtime_hints": {},
+    "files": {},
+    "mounts": {}
+  },
+  "included_profiles": []
+}
+```
+
+## Error Handling
+
+Git mount errors during instance startup are non-blocking:
+- Missing repository: Mount skipped, warning logged
+- Clone failure: Mount skipped, warning logged
+- Invalid paths: Mount skipped, warning logged
+- Branch checkout failure: Falls back to current branch, warning logged
+
+Instance startup continues normally even if some git mounts fail.
+
+## Profile Resolution
+
+When a profile includes other profiles, git mounts are merged:
+- Same `repo_id` + `target_path` combo: later profile overrides
+- Different combos: both are kept
+- Branch conflicts: later profile wins
+
+Example:
+```
+Base Profile:     git_mounts = [{repo_a, /app, main}]
+Included Profile: git_mounts = [{repo_a, /app, develop}, {repo_b, /data}]
+Resolved:         git_mounts = [{repo_a, /app, develop}, {repo_b, /data}]
+```

+# Terminal API
+
+The Terminal API provides WebSocket-based terminal access to running tool instances.
+
+## WebSocket Endpoint
+
+### Connect to Terminal
+
+```
+GET /ws/tool-instances/{instance_id}/terminal
+```
+
+Establishes a WebSocket connection to an interactive terminal session inside a running tool instance container.
+
+**Authentication:** Requires valid session cookie.
+
+**Path Parameters:**
+- `instance_id` (string, UUID): The tool instance ID
+
+**Connection Flow:**
+1. Client connects to WebSocket endpoint
+2. Server authenticates user and verifies instance ownership
+3. Server creates or reattaches to existing terminal session
+4. Server sends `{"type": "status", "status": "connected"}` message
+5. Bidirectional communication begins
+
+**Message Types:**
+
+#### Client to Server
+
+**Terminal Input (bytes or string)**
+- Send raw bytes for terminal input (key presses)
+- Send text for terminal input (will be encoded as UTF-8)
+
+**Resize Command (JSON)**
+```json
+{
+  "type": "resize",
+  "cols": 80,
+  "rows": 24
+}
+```
+
+**Reset Command (JSON)**
+```json
+{
+  "type": "reset"
+}
+```
+Kills the current terminal session and starts a fresh one.
+
+**Pong Response (JSON)**
+```json
+{
+  "type": "pong"
+}
+```
+Sent automatically in response to server ping messages.
+
+#### Server to Client
+
+**Terminal Output (bytes)**
+Raw terminal output as binary data (Blob in browser).
+
+**Status Messages (JSON)**
+```json
+{"type": "status", "status": "connected"}
+{"type": "status", "status": "resetting"}
+```
+
+**Ping Messages (JSON)**
+```json
+{"type": "ping"}
+```
+Sent every 30 seconds to detect disconnections. Client should respond with `{"type": "pong"}`.
+
+### Session Persistence
+
+Terminal sessions persist across WebSocket disconnections:
+- When a client disconnects, the terminal session remains active
+- On reconnection, the client reattaches to the existing session
+- Buffered output is replayed to the client on reconnection
+- Sessions are cleaned up after 30 minutes of inactivity
+
+### Concurrent Connections
+
+Only one WebSocket connection is allowed per terminal session:
+- New connections close existing connections with code 4000
+- Previous client receives "New connection established" reason
+
+## HTTP Endpoints
+
+### Reset Terminal Session
+
+```
+POST /api/projects/{project_id}/repositories/{repo_id}/instances/{instance_id}/terminal/reset
+```
+
+Resets the terminal session for a tool instance, killing the current shell and starting fresh.
+
+**Authentication:** Required
+
+**Path Parameters:**
+- `project_id` (string, UUID): Project ID
+- `repo_id` (string, UUID): Repository ID
+- `instance_id` (string, UUID): Instance ID
+
+**Response:**
+```json
+{
+  "status": "success",
+  "message": "Terminal session reset successfully",
+  "instance_id": "...",
+  "session_id": "..."
+}
+```
+
+**Error Responses:**
+- `404 Not Found`: Instance not found
+- `400 Bad Request`: Instance is not running
+- `500 Internal Server Error`: Failed to reset terminal session
+
+## Error Codes
+
+WebSocket close codes:
+- `1000`: Normal closure
+- `4000`: Error/reset
+- `4001`: Invalid instance ID
+- `4003`: Unauthorized/Forbidden
+- `4004`: Instance not found or not running
+
+## Heartbeat
+
+The server sends ping messages every 30 seconds. If no ping is received for 60 seconds, the client should assume the connection is dead and reconnect.
