## Summary by CodeRabbit
- **New Features**
- Documents now automatically track and display "created by" and "updated by" user information.
- Document creation and update timestamps are now managed and shown more accurately.
- Workspace and document metadata (name, avatar) updates are more responsive and reliable.
- Document creation supports middleware for customizing properties and behavior.
- **Improvements**
- Simplified and unified event handling for document list updates, reducing redundant event subscriptions.
- Enhanced integration of editor and theme settings into the document creation process.
- Explicit Yjs document initialization for improved workspace stability and reliability.
- Consolidated journal-related metadata display in document icons and titles for clarity.
- **Bug Fixes**
- Fixed inconsistencies in how workspace and document names are set and updated.
- Improved accuracy of "last updated" indicators by handling timestamps automatically.
- **Refactor**
- Removed deprecated event subjects and direct metadata manipulation in favor of more robust, reactive patterns.
- Streamlined document creation logic across various features (quick search, journal, recording, etc.).
- Simplified user avatar display components and removed cloud metadata dependencies.
- Removed legacy editor setting and theme service dependencies from multiple modules.
- **Chores**
- Updated internal APIs and interfaces to support new metadata and event handling mechanisms.
- Cleaned up unused code and dependencies related to editor settings and theme services.
- Skipped flaky end-to-end test to improve test suite stability.

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
Relocated AI-related code from `presets` directory to a dedicated `ai` directory for better organization and maintainability.
### What changed?
- Moved AI-related code from `blocksuite/presets/ai` to `blocksuite/ai`
- Relocated AI chat block code from `blocksuite/blocks` to `blocksuite/ai/blocks`
- Updated imports across files to reflect new directory structure
- Renamed `registerBlocksuitePresetsCustomComponents` to `registerAIEffects`
- Fixed path references in GitHub workflow file
### How to test?
1. Build and run the application
2. Verify AI functionality works as expected:
- Test AI chat blocks
- Check AI panel functionality
- Verify AI copilot features
- Ensure AI-related UI components render correctly
### Why make this change?
This restructuring improves code organization by:
- Giving AI features a dedicated directory that better reflects their importance
- Making the codebase more maintainable by grouping related AI functionality
- Reducing confusion by removing AI code from the more general `presets` directory
- Creating clearer boundaries between AI and non-AI related code
