felixxia-oai e4bd7871b1 Add read-only evidence retrieval tools for Guardian reviewers (#59994) ...

## What changed

- Expose `guardian_board` tools to list channels and threads, search posts, and read evidence through a captured read-only view. Require a Guardian storage namespace and keep reads within the review's fixed cutoff, including searches across unsubscribed channels.
- Support literal, case-insensitive searches over decoded JSON fields and nested function-call arguments so quotes, Windows paths, and Unicode escapes do not hide matching evidence.
- Strip response-envelope harness metadata from captured evidence except for `user_input_order`, preserving message payloads and source ordering.

## Testing

Add retrieval coverage for unsubscribed channels, fixed cutoffs, and escaped JSON searches. Update evidence tests to verify serialized payloads retain source order while excluding other harness metadata.
