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inventory (FN-8058 `fn_task_logs_read`), and merger whitespace-classification mocks (execFile `git diff -p -w :2: :3:`) out of date, so all four test shards failed.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  ## Summary by CodeRabbit - **New Features** - Improved project data isolation across backend operations. - Added safer optional toast handling when UI components render outside the full application shell. - Added support for reading task logs during agent heartbeat sessions. - **Bug Fixes** - Prevented runtime probes from hanging and avoided scanning large binary files. - Improved path handling for workspaces with missing descendants. - Corrected task retry state resets and GitHub import/issue-close behavior. - **Style** - Improved chat, terminal, and settings spacing. - Added clearer accessibility labeling for the auto-merge control.

-summary: Page GitHub issue import and keep linked issues closing when tasks reach Done.
+summary: GitHub import pages all open issues with Prev/Next; linked issues close when tasks reach Done.
 category: feature
 dev: The import picker (GitHubImportModal) fetches up to 300 open issues in one request and pages the result client-side at 30/page with Prev/Next controls and a page indicator; a truncation notice appears past the cap. NewTaskModal's reference picker limit rose 30→100. GitHubClient.listIssues now pages the REST path (per_page loop until limit/exhaustion, PR-filtering no longer stops paging early) and lifts the gh path's 100 cap (gh --limit paginates internally); gh-CLI label filtering fetches the full cap before client-side OR filtering. Separately, the GitHub-tracking reconcile sweep now isolates its three passes in runSweep so a throw in one pass no longer silently starves the others — previously a failure in the first pass disabled the entire close-on-Done backstop, leaving linked/imported issues open; failures are now logged instead of swallowed.
