fix: address code review findings across backend and frontend

Fix goroutine-unsafe ULID entropy by wrapping in LockedMonotonicReader.
Move PRAGMA foreign_keys outside transaction in v3 migration where
SQLite was silently ignoring it. Escape LIKE wildcards in link
resolution to prevent false matches. Add non-localhost binding warning,
log writeJSON encoder errors, add ?permanent=true for explicit hard
delete, preserve title/description during absorb, use millisecond
backup timestamps, add path.Clean to spaHandler. Frontend gains
checkedJSON() for resp.ok validation, consistent stopPropagation, and
shared renderCardSections() to eliminate duplicate rendering.

+# Code Review Fixes
+
+## Phase 1: Critical — Concurrency & Data Safety
+
+### 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/...`
+
+### 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
+
+### 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 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`)
