### TL;DR
Moved outline functionality into a dedicated fragment package and updated vanilla-extract CSS dependency.
### What changed?
- Created new `@blocksuite/affine-fragment-outline` package
- Relocated outline-related code from presets to the new fragment package
- Updated imports across affected files to reference the new package location
- Upgraded `@vanilla-extract/css` dependency from 1.14.0/1.16.1 to 1.17.0
- Added necessary package configuration and TypeScript setup for the new fragment
### How to test?
1. Verify outline functionality works as expected in both desktop and mobile views
2. Check that outline panel, viewer, and mobile menu components render correctly
3. Ensure outline navigation and interactions continue to work
4. Confirm no regressions in outline-related features
### Why make this change?
This change improves code organization by isolating outline functionality into a dedicated package, following the modular architecture pattern. This makes the codebase more maintainable and allows for better separation of concerns. The vanilla-extract CSS upgrade ensures consistency across packages and provides access to the latest features and fixes.
### TL;DR
Moved frame management functionality from `blocksuite/blocks` to `@blocksuite/affine-block-frame` package.
### What changed?
- Relocated `frame-manager.ts` from `blocksuite/blocks` to `@blocksuite/affine-block-frame`
- Added new dependencies to block-frame package: `@blocksuite/affine-block-surface` and `yjs`
- Updated imports across multiple components to reference frame manager from its new location
- Moved utility functions `areSetsEqual` and `isFrameBlock` into frame-manager file
- Replaced direct EdgelessRootService references with GfxController in frame panel components
### How to test?
1. Verify frame functionality works in edgeless mode
2. Test frame creation, selection, and manipulation
3. Confirm frame navigation and presentation modes operate correctly
4. Check that frame panel and toolbar interactions remain functional
### Why make this change?
This refactoring improves code organization by consolidating frame-related functionality into a dedicated package, making the codebase more modular and easier to maintain. It also reduces dependencies between packages and provides clearer boundaries for frame-related features.
`@blocksuite/affine` is indirectly depended by electron package. It has around 120k files in total and will greatly slow down forge package build speed.
Move them to peer dependencies to mitigate the issue.
Close [BS-2315](https://linear.app/affine-design/issue/BS-2315/page-block-header)
### What Changes
- Add header toolbar to page block (the first note in canvas)
- Add e2e tests
- Add some edgeless e2e test utils. **The package `@blocksuite/affine` was added to `"@affine-test/kit"`**
