This PR adds word/character diff for expanded diff hunks that have both
a deleted and added section, as well as a setting `word_diff_enabled` to
enable/disable word diffs per language.
- `word_diff_enabled`: Defaults to true. Whether or not expanded diff
hunks will show word diff highlights when they're able to.

### Architecture
I had three architecture goals I wanted to have when adding word diff
support:
- Caching: We should only calculate word diffs once and save the result.
This is because calculating word diffs can be expensive, and Zed should
always be responsive.
- Don't block the main thread: Word diffs should be computed in the
background to prevent hanging Zed.
- Lazy calculation: We should calculate word diffs for buffers that are
not visible to a user.
To accomplish the three goals, word diffs are computed as a part of
`BufferDiff` diff hunk processing because it happens on a background
thread, is cached until the file is edited, and is only refreshed for
open buffers.
My original implementation calculated word diffs every frame in the
Editor element. This had the benefit of lazy evaluation because it only
calculated visible frames, but it didn't have caching for the
calculations, and the code wasn't organized. Because the hunk
calculations would happen in two separate places instead of just
`BufferDiff`. Finally, it always happened on the main thread because it
was during the `EditorElement` layout phase.
I used Zed's
[`diff_internal`](https://github.com/zed-industries/zed/blob/02b2aa6c50c03d3005bec2effbc9f87161fbb1e8/crates/language/src/text_diff.rs#L230-L267)
as a starting place for word diff calculations because it uses
`Imara_diff` behind the scenes and already has language-specific
support.
#### Future Improvements
In the future, we could add `AST` based word diff highlights, e.g.
https://github.com/zed-industries/zed/pull/43691.
Release Notes:
- git: Show word diff highlight in expanded diff hunks with less than 5
lines.
- git: Add `word_diff_enabled` as a language setting that defaults to
true.

Also tidies up error notifications so that in the case of syntax errors
we don't see noise about the migration failing as well.
Release Notes:
- Invalid values in settings files will no longer prevent the rest of
the file from being parsed.
Deals with https://github.com/zed-industries/zed/issues/5259
Highlights brackets with different colors based on their depth.
Uses existing tree-sitter queries from brackets.scm to find brackets,
uses theme's accents to color them.
https://github.com/user-attachments/assets/cc5f3aba-22fa-446d-9af7-ba6e772029da
1. Adds `colorize_brackets` language setting that allows, per language
or globally for all languages, to configure whether Zed should color the
brackets for a particular language.
Disabled for all languages by default.
2. Any given language can opt-out a certain bracket pair by amending the
brackets.scm like `("\"" @open "\"" @close) ` -> `(("\"" @open "\""
@close) (#set! rainbow.exclude))`
3. Brackets are using colors from theme accents, which can be overridden
as
```jsonc
"theme_overrides": {
"One Dark": {
"accents": ["#ff69b4", "#7fff00", "#ff1493", "#00ffff", "#ff8c00", "#9400d3"]
}
},
```
Release Notes:
- Added bracket colorization (rainbow brackets) support. Use
`colorize_brackets` language setting to enable.

There was a TODO in `crates/settings/src/settings_content/theme.rs` to
make this rename.
This PR is just splitting off this change from
https://github.com/zed-industries/zed/pull/40035 to make reviewing that
one a bit easier since that PR is a bit more involved than expected.

Closes #ISSUE
Includes the start of how we can get rid of most of the `.unimplemented`
"Edit in JSON" buttons in the settings UI. For now only Theme selection
is implemented, follow ups will add more settings

Follow up to https://github.com/zed-industries/zed/pull/39468.
Unlike `agent_ui_font_size`, the `agent_buffer_font_size` setting does
have a default value, which means it does not fall back to the regular
UI font size, but rather to its default value.
Release Notes:
- N/A
The panic happened when a user had a settings file with a buffer line
height custom variant, because the drop-down renderer only took into
account the two named variants.
The fix for this will be creating a custom element that allows a user to
manually input a line height greater than one or select either
Comfortable or Standard.
Release Notes:

The font picker from onboarding is a lot friendlier to interact with and
makes it impossible for a user to select an invalid font from the
settings ui.
I also moved the font picker from the onboarding crate to the ui_input
crate

This PR adds the numeric stepper component to the settings ui and
implements some settings that rely on this component as well.
I also switched {buffer/ui}_font_weight to the `gpui::FontWeight` type
and added a manual implementation of the Schemars trait. This allows Zed
to send min, max, and default information to the JSON LSP when a user is
manually editing the settings file.
The numeric stepper elements added to the settings ui are below:
- ui font size
- ui font weight
- Buffer font size
- Buffer font weight
- Scroll sensitivity
- Fast scroll sensitivity
- Vertical scroll margin
- Horizontal scroll margin
- Inline blame padding
- Inline blame delay
- Inline blame min column
- Unnecessary code fade
- Tab Size
- Hover popover delay

Closes https://github.com/zed-industries/zed/issues/39406
Follow up to https://github.com/zed-industries/zed/pull/38726
This PR introduces the `agent_buffer_font_size` setting and renames
`agent_font_size` to `agent_ui_font_size`. This allows whoever wants
`buffer_font_size` and `agent_buffer_font_size` to match, as well as
folks who want a slightly smaller size only in the agent panel (which...
also looks just better by default!).
Release Notes:
- agent: Introduced the `agent_buffer_font_size` setting and renamed
`agent_font_size` to `agent_ui_font_size`, allowing for granular buffer
font size control in the agent panel vs. regular editors.
This PR starts the process of adding each setting field manually to
their respective page in the UI and organizes user/project fields as
well. The next major step is implementing a numeric stepper component,
and handling discriminate union enums as well.
I also did some minor polish in this PR as well
- Switches now use accent color
- Fixed text input rendering with zero width
- Made setting pages scrollable
- Set drop down context menu style to outline
Release Notes:
- N/A

When we refactored settings to not pass JSON blobs around, we ended up
needing
to write *a lot* of code that just merged things (like json merge used
to do).
Use a derive macro to prevent typos in this logic.

Release Notes:
- settings: Major internal changes to settings. The primary user-facing
effect is that some settings which did not make sense in project
settings files are no-longer read from there. (For example the inline
blame settings)
