Adds the Altimate validation framework to altimate-code.

CLI commands:
- `altimate-code validate configure --api-key <key>` — registers API key
  with validation server, saves to ~/.altimate-code/settings.json
- `altimate-code validate install` — manually install /validate skill
- `altimate-code validate status` — check installation state

Auto-setup on every InstanceBootstrap (startup):
- Writes SKILL.md + batch_validate.py to ~/.claude/skills/validate/
- Writes logger hook to ~/.claude/hooks/altimate_logger_hook.py
- Registers hook in ~/.claude/settings.json under hooks.Stop
- Uses bare identifier references (declare const) for build-time define
  constants so Bun's bundler correctly inlines asset content into the binary

Conversation logger (conversation-logger.ts):
- Subscribes to SessionStatus idle events after each turn
- Posts user prompt, tool calls, and assistant response to /log-conversation
- Fire-and-forget — never blocks the session
- Disabled via ALTIMATE_LOGGER_DISABLED=true

/validate skill routing:
- session.ts resolvePrompt() intercepts prompts starting with /validate
  and dispatches as SessionPrompt.command instead of a normal chat turn

Docs:
- README: Validation section covering what it does, setup steps,
  natural language usage examples, and what happens without configuration
- docs/docs/configure/logging.md: detailed data collection reference

…, and enhanced dashboard

- Add `--production --from --to [--limit]` mode to validate production traces
  without requiring a user ID
- Add `validate_production()` function in `batch_validate.py` calling
  `/validate/production` endpoint
- Move semantic matching and reason generation server-side — remove client-side
  Steps 2-3, replace with `claims_psv` field parsing
- Restructure dashboard (Step 5) with radar chart, heatmap, cost/token
  breakdown, collapsible per-trace details
- Update column formats to use new `claims_psv` 12-column pipe-separated format
- Move log file inside report directory for cleaner output organization
- Increase bash timeout from 60 minutes to 8 hours for long-running validations
- Add `@altimateai/altimate-core-darwin-arm64` dependency
