## Summary
Follow-up to #1947. The full-suite on `main` is still red on 3 surfaces
introduced by post-#1947 commits. This PR fixes the two real test
failures and the i18n parity gap.
## Fixes
- **i18n key parity (FN-7658)** —
`settings.scheduling.autoArchiveDuplicateTasks` + `...Help` were added
to `en` but not the 5 non-en catalogs, breaking the i18n parity gate
(`parity.test.ts`, `i18n-gate-coverage.test.ts`). Added the 2 keys
(empty-string per the untranslated-entry convention) to `zh-CN`,
`zh-TW`, `fr`, `es`, `ko` in `packages/i18n/locales` (the single source
of truth; `dashboard/app/locales` is gitignored and synced in CI).
- **chat.test.ts (FN-7675)** — `chat.ts` now imports
`FUSION_RUNTIME_SELF_AWARENESS` from `@fusion/core` (CHAT_SYSTEM_PROMPT
embeds it); the hand-written core mock didn't stub it, so the module
failed to load. Added a stub (importOriginal intentionally avoided to
preserve the fs-cascade block).
- **verification-followup-dedup.test.ts (FN-7658)** — the "remains
additive with FN-4892 same-agent duplicate intake" test asserts the
ARCHIVE path, but FN-7658 made same-agent auto-archiving opt-in
(`autoArchiveDuplicateTasksEnabled` defaults false → flag-in-place in
triage). The test now opts into the legacy archive behavior it asserts.
## Note on shard-2 engine[2/2] timeout
The full-suite shard 2 times out on `@fusion/engine [2/2]` (watchdog
900s). Locally `[2/2]` runs in ~96s and is green (the lone
`provider-registration.test.ts` failure is local-only `pi-ai@0.79.9`
staleness — the lockfile pins `0.80.3` which exports `/compat`, so CI
resolves it). The `verification-followup-dedup` failure above is the
only real `[2/2]` defect; this PR fixes it. If the CI timeout persists
it's aggregate real-git load, which I'll address separately (not a code
bug).
## Verification
- i18n `parity` + `i18n-gate-coverage`: 7/7 ✅
- `chat.test.ts`: 14/14 ✅
- `verification-followup-dedup`: 5/5 ✅
- engine `--shard=2/2` (excluding the local-staleness file): 363 files /
4483 tests ✅ in ~96s
No production behavior change; no changeset needed (i18n catalog +
test-only).

## Summary by CodeRabbit
* **New Features**
* Added scheduling settings for automatic duplicate-task archiving,
including label and help text entries (currently placeholders) across
Spanish, French, Korean, Simplified Chinese, and Traditional Chinese.
* **Bug Fixes**
* Updated “awaiting confirmation” merger messaging to better reflect
when auto-merge proceeds automatically.
* **Tests**
* Updated reliability interaction tests to explicitly opt into legacy
duplicate-task archiving behavior.
* Adjusted chat-related tests by extending the runtime mock to satisfy a
new core import requirement.
