## Summary
- Add Bear `.bear2bk` backup importer (TextBundle-based zip format)
- Enhance markdown zip import to preserve folder structure from zip
paths
- Add colored highlight (`<mark data-color="...">`) support to HTML
adapter
### Bear Import Details
Bear backups are zip archives of TextBundle directories. The importer:
- Parses Bear-specific markdown (highlights `==text==`, callouts `>
[!NOTE]`, inline tags `#tag`)
- Extracts creation/modification dates from `info.json` metadata
- Filters out trashed notes
- Converts Bear tags to AFFiNE tags (consolidated by root segment)
- Builds folder hierarchy from nested tag paths (e.g.,
`#work/projects/alpha`)
- Uses JSZip for lazy decompression to handle large backups without OOM
### Markdown Zip Folder Hierarchy
`importMarkdownZip` now returns `{ docIds, folderHierarchy }` instead of
just `docIds[]`, enabling the UI to recreate the zip's directory
structure as AFFiNE folders.
## Related Issues
- Implements the TextBundle-based import approach suggested in #14115 /
Discussion #14142
- Addresses folder structure preservation requested in #10003
- Partially addresses frontmatter metadata import from #11286
## Test Plan
- [ ] Import a Bear `.bear2bk` backup file via the import dialog
- [ ] Verify tags are created and assigned to documents
- [ ] Verify folder hierarchy matches Bear's nested tag structure
- [ ] Verify creation/modification dates are preserved
- [ ] Verify highlighted text and callouts render correctly
- [ ] Verify images and attachments are imported
- [ ] Import a markdown zip with nested folders, verify folder structure
is recreated
- [ ] Verify trashed Bear notes are excluded

1. **Major Architectural Change: Schema Management**
- Moved from `workspace.schema` to `store.schema` throughout the codebase
- Removed schema property from Workspace and Doc interfaces
- Added `BlockSchemaExtension` pattern across multiple block types
2. **Block Schema Extensions Added**
- Added new `BlockSchemaExtension` to numerous block types including:
- DataView, Surface, Attachment, Bookmark, Code
- Database, Divider, EdgelessText, Embed blocks (Figma, Github, HTML, etc.)
- Frame, Image, Latex, List, Note, Paragraph
- Root, Surface Reference, Table blocks
3. **Import/Export System Updates**
- Updated import functions to accept `schema` parameter:
- `importHTMLToDoc`
- `importHTMLZip`
- `importMarkdownToDoc`
- `importMarkdownZip`
- `importNotionZip`
- Modified export functions to use new schema pattern
4. **Test Infrastructure Updates**
- Updated test files to use new schema extensions
- Modified test document creation to include schema extensions
- Removed direct schema registration in favor of extensions
5. **Service Layer Changes**
- Updated various services to use `getAFFiNEWorkspaceSchema()`
- Modified transformer initialization to use document schema
- Updated collection initialization patterns
6. **Version Management**
- Removed version-related properties and methods from:
- `WorkspaceMetaImpl`
- `TestMeta`
- `DocImpl`
- Removed `blockVersions` and `workspaceVersion/pageVersion`
7. **Store and Extension Updates**
- Added new store extensions and adapters
- Updated store initialization patterns
- Added new schema-related functionality in store extension
This PR represents a significant architectural shift in how schemas are managed, moving from a workspace-centric to a store-centric approach, while introducing a more extensible block schema system through `BlockSchemaExtension`. The changes touch multiple layers of the application including core functionality, services, testing infrastructure, and import/export capabilities.
