ioanbudea-OAI 6574bcdba8 Defer synchronous Guardian heartbeat compression to preparation (#57519) ...

## What changed

Keep original scheduled messages and heartbeat provenance during synchronous transcript collection. Add `prepare_sync_context` to compress repeated heartbeat instructions across the complete collected transcript before selecting the requested suffix, preserving reference numbering in full and delta prompts.

Route synchronous reviewer prompts through this preparation step and reject composition of unprepared scheduled messages. Move transcript profiles and REPL evidence rendering into the preparation module. Asynchronous heartbeat compression remains in collection.

## Testing

Extend heartbeat transcript coverage to compare prepared full and delta prompts with the existing rendering and verify that direct composition rejects unprepared scheduled messages.
