After context compression in an active conversation, scrolling to the top
would not load earlier messages because useThreadRuns was never invalidated
once new runs completed. The stale runs list left hasMore permanently false.
- Invalidate the ["thread", threadId] query in onFinish so the runs list
stays current as new runs are created
- Split the useThreadHistory effect into separate reset (threadId change)
and incremental-update (runs.data change) paths so indexRef is adjusted
without resetting already-loaded history
- Add message deduplication when prepending loaded run messages to guard
against overlap with the live stream
- Extract deduplicateHistoryMessages and adjustHistoryIndex into a pure
utility module with 10 unit tests
Closes#2965
* fix: bucket subagent token usage into RunRow.subagent_tokens
Add caller-bucketed token tracking to RunJournal so subagent and
middleware LLM calls are written to the correct RunRow columns instead
of all falling into lead_agent_tokens (default 0).
- RunJournal: accumulate _lead_agent_tokens / _subagent_tokens /
_middleware_tokens in on_llm_end, deduped by langchain run_id.
Add record_external_llm_usage_records() for external sources
(respects track_token_usage flag). Return caller buckets from
get_completion_data().
- SubagentTokenCollector: new lightweight callback handler that
collects LLM usage within subagent execution.
- SubagentExecutor: wire collector into subagent run_config and sync
records to SubagentResult on every chunk (timeout/cancel safe).
- SubagentResult: add token_usage_records and usage_reported fields.
- task_tool: report subagent usage to parent RunJournal on every
terminal status (COMPLETED/FAILED/CANCELLED/TIMED_OUT), including
the CancelledError path, guarded against double-reporting.
No DB migration needed — RunRow columns already exist.

* fix(frontend): unify gateway-config localhost fallback for prod (#2705)
`getGatewayConfig()` only fell back to localhost defaults when
`NODE_ENV === "development"`, while `next.config.js` always falls back
to `127.0.0.1:8001`. Running `make start` (which sets NODE_ENV=production
via `next start`) without `DEER_FLOW_INTERNAL_GATEWAY_BASE_URL` /
`DEER_FLOW_TRUSTED_ORIGINS` therefore caused zod to throw inside SSR
layouts and surfaced as a 500.
Drop the NODE_ENV gating and use localhost defaults everywhere — the
"force explicit config in prod" intent should be enforced by deployment
templates (docker-compose already sets both vars), not by request-time
crashes. Document the two vars in both .env.example files and add unit
coverage for the dev/prod env-unset paths.

* feat: set up Vitest frontend testing infrastructure with CI workflow
Migrate existing 4 frontend test files from Node.js native test runner
(node:test + node:assert/strict) to Vitest, reorganize test directory
structure under tests/unit/ mirroring src/ layout, and add a dedicated
CI workflow for frontend unit tests.
- Add vitest as devDependency, remove tsx
- Create vitest.config.ts with @/ path alias
- Migrate tests to Vitest API (test/expect/vi)
- Rename .mjs test files to .ts
- Move tests from src/ to tests/unit/ (mirrors src/ layout)
- Add frontend/Makefile `test` target
- Add .github/workflows/frontend-unit-tests.yml (parallel to backend)
- Update CONTRIBUTING.md, README.md, AGENTS.md, CLAUDE.md
