## Embedding Tracker & Prompt Submit Query Fixes

Implemented a plan to fix two critical bugs in the Signet daemon's memory pipeline:

**Bug 1 – Embedding Tracker Crash**: The INSERT statement in `embedding-tracker.ts:135` was missing the `dimensions` column, causing NOT NULL constraint failures. This was fixed by adding `dimensions` to both the INSERT and ON CONFLICT UPDATE clauses, passing `vector.length` as the dimensions value.

**Bug 2 – Prompt Submit Recall Queries Broken**: The `user-prompt-submit` hook was building garbage FTS recall queries due to two upstream issues:
- **Claude Code path**: The CLI at `cli.ts:4816` was only checking `parsed.user_prompt || parsed.userPrompt`, but Claude Code sends `{ prompt: "..." }` on stdin. Fixed by adding `parsed.prompt` as the first fallback.
- **OpenClaw adapter path**: OpenClaw's `before_agent_start` event passes the entire formatted prompt (including metadata preamble with conversation info, sender, untrusted content markers) instead of just the user's message. Fixed by implementing `extractUserMessage()` to strip metadata patterns and return only the actual user message text.

## Files Modified

1. `packages/daemon/src/embedding-tracker.ts` – Added `dimensions` column handling (already completed)
2. `packages/cli/src/cli.ts` – Updated stdin field resolution to check `parsed.prompt` first
3. `packages/adapters/openclaw/src/index.ts` – Implemented metadata extraction logic at line 881

## Verification Plan

- Rebuild daemon and verify no more embedding constraint errors
- Test CLI stdin parsing with `echo '{"prompt":"test query"}' | bun cli.ts hook user-prompt-submit`
- Monitor daemon logs for recall queries using actual user message words instead of metadata keywords
- Run full test suite and typecheck
