[email protected]andClaude Opus 4.6 7532065590 feat(workspace): metadata-driven indexing/hygiene, document versioning, and patch support
Foundation for the extensible frontend system. Workspace documents now
support metadata flags (skip_indexing, skip_versioning, hygiene config)
via folder-level .config documents and per-file overrides, replacing
hardcoded hygiene targets and indexing behavior.

Key changes:
- DocumentMetadata type with resolution chain (doc → folder .config → defaults)
- Document versioning: auto-saves previous content on write/append/patch
- Workspace patch: search-and-replace editing via memory_write tool
- Hygiene rewrite: discovers cleanup targets from .config metadata
  instead of hardcoded daily/ and conversations/ directories
- memory_read gains version/list_versions params
- memory_write gains metadata/old_string/new_string/replace_all params
- V14 migration adds memory_document_versions table (both PG + libSQL)
