- docs/adapters/browser/xiaohongshu.md: fill in search command description
(was empty), update usage examples with keyword positional arg
- TESTING.md: update unit test count 31→32 (search.test.ts added in #298),
add xiaohongshu/search.test.ts to the adapter test file list
## Changes
### E2E Test Suite (~52 test cases)
- public-commands.test.ts — Public API commands (hackernews, v2ex)
- browser-public.test.ts — Browser commands for public data across all sites
- browser-auth.test.ts — Graceful failure verification for login-required commands
- management.test.ts — Full coverage of management commands
- output-formats.test.ts — Output format validation (json/yaml/csv/md)
- smoke/api-health.test.ts — Scheduled API health checks
### Auto-detect Browser Mode
- buildMcpArgs uses CI env var to select mode:
- Local (no CI) → --extension (connect to user's Chrome)
- CI → standalone (launches its own browser)
### CI Pipeline
- e2e-headed.yml — Real Chrome via setup-chrome + xvfb in headed mode
- ci.yml — build + unit-test (2 shards) + smoke-test (scheduled/manual)
- Composite action for shared Chrome + xvfb setup
### Documentation
- New TESTING.md — Architecture, coverage, local setup, how to add tests
