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.
### TL;DR
Refactored `SpecProvider` singleton access pattern and reorganized adapter/extension code structure.
### What changed?
- Changed `SpecProvider.getInstance()` to `SpecProvider._` for cleaner singleton access
- Moved adapter/extension code from `_common` directory to dedicated `adapters` and `extensions` folders
- Consolidated adapter extensions into a single file
- Removed unused dependencies from package.json
- Deleted unnecessary schema files
- Extracted `MobileSpecsPatches` class into the mobile patching code
- Updated all references to use the new `SpecProvider._` accessor
### How to test?
- Verify all specs are properly registered and accessible via `SpecProvider._`
- Test adapter functionality for HTML, Markdown, Notion HTML and plain text
- Check mobile-specific features and patches work correctly
- Ensure preview functionality works in both page and edgeless modes
### Why make this change?
- Improves code organization by properly separating adapters and extensions
- Simplifies singleton access pattern
- Removes unnecessary dependencies and files
- Makes the codebase more maintainable by consolidating related functionality
