Critical Bug Fix: Worker Initialization Failure

v9.1.0 was unable to initialize its database on existing installations. This patch fixes the root cause and several related issues.

Fix FOREIGN KEY constraint failure during migration — The addOnUpdateCascadeToForeignKeys migration (schema v21) crashed when orphaned observations existed (observations whose memory_session_id has no matching row in sdk_sessions). Fixed by disabling FK checks (PRAGMA foreign_keys = OFF) during table recreation, following SQLite's recommended migration pattern.
Remove hardcoded CHECK constraints on observation type column — Multiple locations enforced CHECK(type IN ('decision', 'bugfix', ...)) but the mode system (v8.0.0+) allows custom observation types, causing constraint violations. Removed all 5 occurrences across SessionStore.ts, migrations.ts, and migrations/runner.ts.
Fix Express middleware ordering for initialization guard — The /api/* guard middleware that waits for DB initialization was registered AFTER routes, so Express matched routes before the guard. Moved guard middleware registration BEFORE route registrations. Added dedicated early handler for /api/context/inject to fail-open during init.

Restored mem-search skill — Recreated plugin/skills/mem-search/SKILL.md with the 3-layer workflow (search → timeline → batch fetch) updated for the current MCP tool set.
