Two bugs fixed:
1. CodeMirror raw editor didn't reflect frontmatter changes (e.g. Trashed: true)
after trash/archive because useCodeMirror only used content as initial state.
Added content-sync effect with external-sync guard to prevent infinite loops.
2. Entry actions (trash/archive/restore/unarchive) showed "Property updated" toast
instead of contextual message because runFrontmatterAndApply overwrote it.
Added silent option to suppress toast when caller manages its own feedback.
