markdown_preview: Add font size settings and actions (#55489)
Add support for scaling the Markdown preview's body text and headings
with `cmd-=` / `cmd--` / `cmd-0`. Previously these shortcuts only
resized code blocks because the preview's body used `ui_font_size` and
headings used a rem-based scale anchored to it, while the keybindings
only mutated `BufferFontSize`.

The preview's scroll subtree is now wrapped in
`WithRemSize(buffer_font_size)`, so `1rem` resolves to the buffer font
size inside the preview. Body text, headings
(`text_3xl`/`text_2xl`/...), and rem-based spacing all scale together.
The outer focus root and scrollbar remain at the UI font size.

Self-Review Checklist:

- [x] I've reviewed my own diff for quality, security, and reliability
- [x] Unsafe blocks (if any) have justifying comments
- [x] The content is consistent with the [UI/UX
checklist](https://github.com/zed-industries/zed/blob/main/CONTRIBUTING.md#uiux-checklist)
- [x] Tests cover the new/changed behavior
- [x] Performance impact has been considered and is acceptable

Closes #55374

Release Notes:

- Added `markdown_preview_font_size` setting and actions to scale
Markdown preview font size separately from the editor.

Licensing

Zed source code is licensed primarily under GPL-3.0-or-later, with Apache-2.0 components where marked.

License information for third party dependencies must be correctly provided for CI to pass.

We use cargo-about to automatically comply with open source licenses. If CI is failing, check the following:

  • Is it showing a no license specified error for a crate you've created? If so, add publish = false under [package] in your crate's Cargo.toml.
  • Is the error failed to satisfy license requirements for a dependency? If so, first determine what license the project has and whether this system is sufficient to comply with this license's requirements. If you're unsure, ask a lawyer. Once you've verified that this system is acceptable add the license's SPDX identifier to the accepted array in script/licenses/zed-licenses.toml.
  • Is cargo-about unable to find the license for a dependency? If so, add a clarification field at the end of script/licenses/zed-licenses.toml, as specified in the cargo-about book.

Zed is developed by Zed Industries, Inc., a for-profit company.

If youd like to financially support the project, you can do so via GitHub Sponsors. Sponsorships go directly to Zed Industries and are used as general company revenue. There are no perks or entitlements associated with sponsorship.
