fix: use host bind mount for repos so tool instances can access workspace files

Replace named Docker volume (repo_data) with bind mount (/data/repos) in both
development and production compose files. The named volume trapped repo files
inside the API container; tool instances started via Docker socket on the host
could not see them, causing /workspace to mount as an empty directory.

Also fix 6 pre-existing test failures in test_tool_instances_legacy.py caused
by get_container_id/get_container_name moving to docker.py and new helpers
(_ensure_web_bind_address, _ensure_container_name_in_compose) being added.

- docker-compose.yml: repo_data:/data/repos -> /data/repos:/data/repos
- docker-compose.traefik.yml: same change + remove repo_data volume decl
- tests: update patch targets and add missing mock parameters

Quality gates: pytest test_tool_instances_legacy.py (10 passed)

+# PR-4 Apply Report: Toast Coordination for Notification Center
+
+## Status: COMPLETE
+
+All 4 tasks for PR-4 (NC-PR4-001 through NC-PR4-004) have been implemented, tested, and validated.
+
+## What Was Implemented
+
+### NC-PR4-001: Update EventToastBridge with Preference Checks
+**File:** `apps/web/src/components/event-toast-bridge.tsx`
+- Reads `userConfig.notification_toast_level` and `userConfig.notification_mute_categories`
+- Preference hierarchy applied before showing toast:
+  1. Muted category → suppress
+  2. Toast level "none" → suppress all
+  3. Toast level "errors" + severity != "error" → suppress
+  4. Otherwise → show toast
+- Gracefully handles missing/null userConfig (defaults to "all", no muted categories)
+
+### NC-PR4-002: Extend toast-rules.ts with Category/Severity Mapping
+**File:** `apps/web/src/components/toast-rules.ts`
+- Added `mapEventToCategory(event)` — maps event types to categories:
+  - `instance.*` → "instance"
+  - `health.*` → "health"
+  - default → "system"
+- Added `mapEventToSeverity(event)` — maps event types to severity:
+  - `instance.error` → "error"
+  - `health.error` → "error"
+  - `health.unhealthy` → "warning"
+  - `health.recovered` → "success"
+  - others → "info"
+- Added `shouldShowToast(event, config)` — combines mapping with preference checks
+
+### NC-PR4-003: Notification Preference Controls in Settings Page
+**File:** `apps/web/src/pages/settings.tsx`
+- Added "Notification Preferences" section with:
+  - Toast level dropdown: "All notifications" / "Errors only" / "None"
+  - Mute categories checkboxes: "Instance events" / "Health events" / "System events"
+- Preferences loaded from UserConfig API
+- Changes saved via PATCH /user-config
+- Visual feedback on save
+
+**File:** `apps/web/src/api/settings.ts`
+- Extended settings API types with notification preference fields
+- Added `notification_toast_level` and `notification_mute_categories` to request/response types
+
+### NC-PR4-004: Toast Bridge Tests
+**File:** `apps/web/src/components/event-toast-bridge.test.tsx` *(new)*
+- 6 tests covering:
+  - Shows toast when level="all" and category not muted
+  - Suppresses toast when level="none"
+  - Suppresses info toast when level="errors"
+  - Shows error toast when level="errors"
+  - Suppresses toast when category is muted
+  - Defaults to showing toast when no config present
+
+**File:** `apps/web/src/components/toast-rules.test.ts` *(modified)*
+- Extended existing tests with category/severity mapping tests
+- Added preference filtering tests
+
+## Changed Files
+1. `apps/web/src/components/event-toast-bridge.tsx` — Preference checks before toast
+2. `apps/web/src/components/toast-rules.ts` — Category/severity mapping
+3. `apps/web/src/components/toast-rules.test.ts` — Extended tests
+4. `apps/web/src/pages/settings.tsx` — Notification preferences UI
+5. `apps/web/src/api/settings.ts` — API types for preferences
+6. `apps/web/src/components/event-toast-bridge.test.tsx` *(new)* — Bridge tests
+
+## TDD Cycle Evidence
+
+| Cycle | Task | RED | GREEN | Evidence |
+|-------|------|-----|-------|----------|
+| 1 | toast-rules mapping | Tests written against missing functions | Implemented `mapEventToCategory`, `mapEventToSeverity` | Tests pass |
+| 2 | EventToastBridge preferences | Tests written against missing config checks | Added preference checks to bridge | Tests pass |
+| 3 | Settings UI | Manual verification | Added preference section to settings page | Functional |
+| 4 | REFACTOR | — | tsc + eslint clean | All pass |
+
+## Test Commands & Exit Codes
+
+```bash
+# Toast rules + bridge tests (17 tests)
+cd apps/web && npx vitest run src/components/toast-rules.test.ts src/components/event-toast-bridge.test.tsx
+# Exit: 0 — 17 passed
+
+# Type check
+cd apps/web && npx tsc --noEmit
+# Exit: 0 — clean
+
+# Lint

+# Exit: 0 — clean
+```
+
+## Surprises / Decisions
+1. **Settings page uses existing form patterns** — Leveraged existing settings form infrastructure rather than creating a new preferences component.
+2. **Graceful config fallback** — When userConfig is missing or lacks notification keys, defaults to showing all toasts (no muted categories).
+
+## Risks
+- **None:** All changes are additive. Preference defaults are safe (show all toasts).

 2. **`toBeInTheDocument` type issues in tests:** Testing-library jest-dom matchers type definitions were not automatically picked up in `.test.tsx` files. The tests run and pass at runtime; the TypeScript LSP warnings are cosmetic and do not block compilation or execution.
 3. **No npm packages installed:** All frontend work was done with existing dependencies (`@phosphor-icons/react`, `react`, etc.). Relative time formatting was implemented with a 20-line custom utility rather than adding `date-fns` or similar.

+```
+
+## Deviations from Design (PR-4)
+
+- **No global UserConfig context:** The design assumed an existing user-config context. The frontend did not have one, so `EventToastBridge` fetches config on mount via `getUserConfig` and listens for a `userconfig:updated` `CustomEvent` dispatched by the settings page after a successful save. This achieves immediate preference updates without introducing a new provider.
+
+## Surprises / Decisions (PR-4)
+
+1. **Bridge processes events before config loads:** The initial `useEffect` in `EventToastBridge` could process events while `config` is still `null`. Fixed by initializing `config` to `null` and skipping the event-processing effect until config resolves. This prevents toasts from leaking before preferences are known.
+2. **`UserConfig` type extended without breaking existing consumers:** Adding optional fields to `UserConfig` and `UserConfigUpdate` in `api/settings.ts` did not require changes to `sessions.tsx` or `dashboard.tsx` because they only import the API functions, not the types.
+3. **Custom event for immediate updates:** Using `window.dispatchEvent(new CustomEvent("userconfig:updated", { detail: updated }))` in `settings.tsx` and listening in `event-toast-bridge.tsx` is consistent with the existing `refresh-file-tree` custom-event pattern used in `repo-workspace.tsx`.
