- Add memory_rename tool (in-place rename, preserves content and links)
- Update rename.agent prompt to use memory_rename() instead of text output
- Fix {{rename}} placeholder to respect --target keys when provided
- Add format_rename_targets() for targeted rename runs
agents/*.agent definitions and prompts/ now live under
src/subconscious/ alongside the code that uses them.
No more intermediate agents/ subdirectory.
