fix(db): add missing 0001_cynical_ultimatum to Drizzle migration journal

The migration file 0001_cynical_ultimatum.sql existed on disk but was not
registered in the Drizzle journal (_journal.json). This caused fresh-database
migrations (CI) to skip creating tables (agent_logs, insights, preferences,
skills, summarization_jobs), then 0002_nebulous_mimic.sql would fail trying
to ALTER the non-existent preferences table.

Fix: insert cynical_ultimatum at idx 1 in the journal and shift all
subsequent entries (idx 2-7).

Verified: pnpm test passes (347 tests, 35 tasks).

+# Scratchpad — fix-ci-migrations-20260330
+
+## Objective
+
+- Fix Drizzle migration journal ordering so fresh Postgres instances apply all schema migrations in CI.
+
+## Plan
+
+- Inspect migration SQL, journal, and snapshot chain.
+- Patch metadata consistently.
+- Run full test suite.
+- Record result and risks.
+
+## Progress
+
+- Inspected migration files and confirmed 0001_cynical_ultimatum.sql is missing from journal while 0002 depends on it.
+- Patched `packages/db/drizzle/meta/_journal.json` to insert `0001_cynical_ultimatum` at idx 1 and shift later entries to idx 2-7.
+- Verified snapshot content is already semantically aligned with the fixed ordering: the missing tables exist in `0001_snapshot.json`, and `mutable` appears in later snapshots.
+- Installed workspace dependencies in this worktree to make the requested test command runnable.
+- Ran `pnpm test` successfully; gateway reported `347 passed (347)` and Turbo finished with `35 successful, 35 total`.
