- Replace minimal Pi note with comprehensive portability table (node:sqlite,
  Node version, architecture, WAL/filesystem considerations)
- Add recommended database path section for Pi (/data/openclaw/workq/workq.db)
  with config example and directory setup commands
- Add 5-step probe/verification command sequence for new host deployments
- Fix hardcoded local path in Installation section to use relative repo path

Enhances workq extension documentation for Claude Code agents with:

- Detailed breakdown of all 8 queue tools with parameters and examples
- Expected call order workflow (claim -> status/files -> in-review -> done)
- Status state machine diagram and valid transitions
- Practical examples covering happy path, conflicts, blocked tasks, queries
- Common pitfalls and integration notes for platform squad agents
- File conflict detection guidance

Provides agents with actionable reference for coordinating work across
the multi-agent fleet.

The previous test used vi.fn() to mock the WorkqDatabase class, but this
doesn't work properly when the actual code uses 'new WorkqDatabase()'.

Changed to use a proper class mock with vi.hoisted() to ensure the mock
functions are available when the vi.mock() factory runs.

All 41 tests now pass.
