feat(tui): include backlinks in link picker

Link picker now shows both outgoing [[links]] and backlinks in
a unified list with section headers. Backlinks follow by entity
ID directly, outgoing links resolve by text. Navigating into a
backlink works the same as following an outgoing link — pushes
to nav stack, esc pops back.

-# Code Review Fixes
+# Code Hardening — Senior Dev Audit Fixes
 
-## Phase 1: Critical — Concurrency & Data Safety
+## Phase 1: Quick Wins (safety + correctness)
+- [x] Cap API list limit at 200
+- [x] Fix markdown XSS — add DOMPurify to sanitize marked output
+- [x] Add missing DB indexes (deleted_at, modified_at) via v4 migration
+- [x] Fix v2 migration error handling (swallowed ALTER TABLE errors)
+- [x] Fix ~/.nib directory permissions (0o755 → 0o700)
 
-### 1. ULID entropy not goroutine-safe
-- [x] Wrap MonotonicEntropy in LockedMonotonicReader (`internal/ulid/ulid.go`)
-- [x] Add concurrent uniqueness test (100 goroutines)
-- [x] Verify `go test -race ./internal/ulid/...`
+## Phase 2: CI Pipeline
+- [x] Gitea Actions workflow: test + lint on PR
 
-### 2. Migration PRAGMA bug
-- [x] Move `PRAGMA foreign_keys = OFF` before transaction in v3 migration (`internal/db/db.go`)
-- [x] Re-enable after commit
-- [x] Remove dead `currentSchema` constant while here
+## Phase 3: context.Context in Store
+- [x] Thread context.Context through all Store methods
+- [x] Use context in API handlers (from r.Context())
+- [x] Use context in CLI commands (cobra context)
 
-### 3. LIKE wildcard injection in link resolution
-- [x] Escape `%` and `_` in link text before LIKE query (`internal/db/links.go`)
-- [x] Add `ESCAPE '\'` clause
-- [ ] Test with `[[%]]` and `[[_]]` link text
+## Phase 4: cmd/ Tests
+- [x] Test add command
+- [x] Test ls command
+- [x] Test promote/demote commands
+- [x] Test delete command
+- [x] Test absorb command
 
-## Phase 2: High — Security & API Hygiene
-
-### 4. No auth warning for non-localhost binding
-- [x] Print loud warning when `--host != 127.0.0.1` and no auth configured (`cmd/serve.go`)
-- [ ] Consider `--no-auth` flag requirement for non-localhost
-
-### 5. writeJSON ignores encoder errors
-- [x] Log error from `json.Encoder.Encode()` in `writeJSON` (`internal/api/helpers.go`)
-
-### 6. DELETE endpoint semantics
-- [x] Add `?permanent=true` query param for hard delete (`internal/api/entities.go`)
-- [x] Add `HardDelete` store method (`internal/db/entities.go`)
-- [ ] Update frontend and CLI to match
-- [x] Keep backward compat: double-delete still works without param
-
-## Phase 3: Medium — Frontend Robustness
-
-### 7. No resp.ok checks on fetch calls
-- [x] Add `checkedJSON()` wrapper with error extraction (`web/app.js`)
-- [x] All API methods use `checkedJSON(resp)` instead of `resp.json()`
-- [ ] Surface API errors to user via notification/toast
-
-### 8. Inconsistent event.stopPropagation
-- [x] Add stopPropagation to all renderStreamPeek action buttons
-- [x] Add stopPropagation to all renderCardPeek action buttons and inline section buttons
-
-### 9. Duplicate section rendering
-- [x] Extract `renderCardSections()` shared function (`web/app.js`)
-- [x] Refactor `renderInlineDetail` to use shared function
-- [x] Refactor `renderCardPeek` to use shared function
-
-## Phase 4: Medium — Data Integrity
-
-### 10. Absorb discards source title/description
-- [x] If target has no title, inherit from source (`internal/db/entities.go`)
-- [x] If target has no description, inherit from source
-- [ ] Test title/description preservation
-
-## Phase 5: Low — Housekeeping & UX
-
-### 11. Backup path collision
-- [x] Use millisecond-precision timestamps (`cmd/backup.go`)
-
-### 12. spaHandler path safety
-- [x] Add explicit `path.Clean` in spaHandler (`internal/api/router.go`)
-
-### 13. Focus-peek escape hatch
-- [ ] Add visible close/back button in focus-peek mode (`web/app.js`)
-
-### 14. Hard delete confirmation
-- [ ] Add confirmation step or undo toast before permanent delete (`web/app.js`)
+## Phase 5: Backup/Export
+- [x] nib export — dump entities to JSON
+- [x] nib backup — safe SQLite backup (handles WAL)
