test: green full-suite CI after main drift (#2229)
## Summary
Restores green **Full Suite (non-blocking)** runs on `main`. Recent main
merges left i18n key parity, schema baseline bookkeeping (0011→0012),
heartbeat tool inventory (FN-8058 `fn_task_logs_read`), and merger
whitespace-classification mocks (execFile `git diff -p -w :2: :3:`) out
of date, so all four test shards failed.
## Root causes observed on main
- **Shard 4 / `@fusion/i18n`**: missing `skipConfirmationDialogs*` +
`reviewBudgetExhausted` in non-en locales; orphan
`awaitingApprovalPlanReviewReplanCap`
- **Shard 3 / `@fusion/core`**: `SCHEMA_BASELINE_VERSION` advanced to
`0012` while tests still equated it with
`OWNER_PROJECT_ID_SPLIT_VERSION` (`0011`) and omitted `0012` from
applied-migration lists
- **Shards 1–2 / `@fusion/engine`**: tool count/snapshot drift for
`fn_task_logs_read`; merger tests still mocked `git diff-tree` for
trivial classification after the execFile `:2:`/`:3:` cutover; mock
provider `updateTask` arity drift
## Changes
- Locale catalogs: add missing keys, drop orphan key
- Schema applier tests: immutable 0011 identity + baseline 0012 lists
- Heartbeat + gating snapshots: include `fn_task_logs_read`
- Merger unit mocks: recognize `git diff -p -w :2:path :3:path`
- Mock provider: accept optional third `updateTask` arg
## Test plan
- [x] `pnpm --filter @fusion/i18n exec vitest run` — 23/23
- [x] `pnpm --filter @fusion/core exec vitest run
src/__tests__/postgres/schema-applier.test.ts` (immutable + automation
upgrade) — pass
- [x] `pnpm --filter @fusion/core exec vitest run` project-identity +
satellite-fusiondir — pass
- [x] Engine suites from failed CI shards (file-scoped,
hermes/openclaw/paperclip/grok, reliability post-finalize/mission,
heartbeat, gating, merger recovery/prompt, mock-provider, etc.) — pass
- [ ] Full Suite workflow green on merge to main
