Summary

Claude Code's hook timeout field is in seconds, not milliseconds. SETUP.md and captain-hook's docs told users to install "timeout": 5000 (intended as 5s), which actually installs an 83-minute cancellation window instead. This was live on real systems, not just theoretical — verified on two machines where karma-installed hooks carried the exact 5000/15000 values straight from the docs.

• Corrects all 144 example timeout values (and the prose claiming milliseconds) across SETUP.md, api/SETUP.md, api/scripts/SETUP.md, captain-hook/README.md, captain-hook/docs/hooks/*, and docs/about/hooks-guide.md.
• Fixes a related real code bug this same confusion caused in karma's own /hooks browser page: HookRegistration.timeout_ms stored the raw (seconds) value from settings.json with no conversion, then displayed it suffixed ms — silently reinforcing the same mistake for anyone using karma to audit their own hooks. Renamed to timeout_seconds end-to-end (Pydantic model, api-types.ts, hooks page template).

Test plan

• pytest -k hook passes (no dedicated hook.py test file exists; ran shell-cron tests to confirm the unrelated timeout_ms field on background_shell was untouched)
• Sanity-instantiated HookRegistration with timeout_seconds and confirmed routers/hooks.py still imports cleanly
• Grepped repo-wide to confirm no remaining 5000/15000-style ms-mistake values or stray timeout_ms references tied to hooks

Fixes #98

Verified against the Claude Code hooks reference: timeout is seconds, so the old docs really did install 83-minute windows. Approving.

What I checked:

• All 136 changed doc values are an exact ÷1000 (5000→5, 2000→2, 15000→15, …) — no stray edits.
• The Bash tool_input.timeout: 120000 example is correctly left in ms (good catch in the second commit).
• timeout_ms → timeout_seconds is renamed end-to-end (model, parser, api-types.ts, hooks page). The remaining timeout_ms refs are background_shells, which is genuinely ms — untouched, correct.
• No installer/script in the repo writes hook timeouts, so docs were the only source of bad values.

Non-blocking follow-ups:

• docs/feature/hooks-page/ui-design.md (not in this diff) still shows timeout: 5000ms / 15000ms / 30000ms in the mockups at lines 223, 231, 240, 284.
• Users who already pasted the old config still have 5000s timeouts. A one-line note in SETUP.md (or a check on the /hooks page flagging timeouts > 600) would help them find it.
