feat(scripts): agent importer — new adapters, RL trajectory output

Extends sync-agents-to-brain.py with:
- cursor, zed, continue, aider, cline adapters (11 total now)
- RL trajectory extraction (state/action/observation triples)
- Improved content flattening for OpenAI/Anthropic multipart content
- Engine: stable per-message timestamps, session_memory.md rendering
