Subject: [PATCH] fix(editor): support markdown transform when using IME
 (#12778)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Fix #12284
Close
[BS-3517](https://linear.app/affine-design/issue/BS-3517/微软新注音输入法无法使用markdown语法)

This PR refactor the markdown transform during inputting, including:
- Transfrom markdown syntax input in `inlineEditor.slots.inputting`,
where we can detect the space character inputed by IME like Microsoft
Bopomofo, but `keydown` event can't.
- Remove `markdown-input.ts` which was used in `KeymapExtension` of
paragraph, and refactor with `InlineMarkdownExtension`
- Adjust existing `InlineMarkdownExtension` since the space is included
in text.
- Add two `InlineMarkdownExtension` for paragraph and list to impl
Heading1-6, number, bullet, to-do list conversion.

Other changes:
- Improve type hint for parameter of `store.addBlock`

## Summary by CodeRabbit

- **New Features**
- Added markdown shortcuts for creating code blocks and dividers in the
rich text editor.
- Introduced enhanced paragraph markdown support for headings and
blockquotes with inline markdown patterns.
- Integrated new list markdown extension supporting numbered, bulleted,
and todo lists with checked states.

- **Improvements**
- Updated markdown formatting patterns to require trailing spaces for
links, LaTeX, and inline styles, improving detection accuracy.
- Markdown transformations now respond to input events instead of
keydown for smoother editing experience.
- Added focus management after markdown transformations to maintain
seamless editing flow.

- **Bug Fixes**
- Removed unnecessary prevention of default behavior on space and
shift-space key presses in list and paragraph editors.

- **Refactor**
- Enhanced event handling and typing for editor input events, improving
reliability and maintainability.
- Refined internal prefix text extraction logic for markdown processing.
