Automated fork sync — clean merge of upstream block/buzz main into fork main. Direct push to main is blocked by the branch ruleset, so this lands as a PR.

Upstream commits merged:

No merge conflicts.

Opened by the scheduled sync-buzz-fork task.

## Summary

Inline code on mobile renders as **bold body text on a faint background
wash** — no monospace face, no chip, and it cannot wrap. block#5257 diagnosed
this as a missing `highlightBuilder`.

That is no longer the right fix. `gpt_markdown` 1.2.0 deprecates
`highlightBuilder` (removal in 2.0.0), renders inline code as a real
chip, and adds `InlineCodeStyle` for restyling it. The package author
confirmed this on the issue. So this PR is an upgrade — 1.1.6 → 1.2.1 —
plus one theme declaration, rather than the builder the issue originally
asked for.

**Where the style is declared.** `GptMarkdownThemeData` goes in
`AppTheme._buildTheme`, which both `light()` and `dark()` call. That
reaches all four `GptMarkdown` call sites — `message_content`,
`transcript_item_widget`, `token_pill`, `custom_emoji_render` — so the
style is stated once instead of per widget. A widget-level
`inlineCodeStyle` would have covered channel messages only, leaving the
other three on the package's defaults.

**What is declared.** Face, size, ink, chip fill and outline — not the
face alone. A face name on its own leaves the rest on the package's
defaults, which put inline code at 14.1sp beside a fenced block's 13, on
a neutral `onSurface` tint rather than the app's code surface. In dark
that tint is *lighter* than the surface, while every other code surface
in the app is recessed, so the chip read as a different kind of object.
All of it now comes from one `CodeStyle` declaration that the fenced
block reads from too, so the two cannot be edited apart.

**Three adaptations the upgrade requires.** Each was found by running
the gate, not by reading the changelog:

1. **`imageBuilder` widened** to `(context, url, width, height)`. This
is a hard compile error, and it is **not listed in the package's
migration guide**, which states "nothing here stops code compiling".
Worth reporting upstream.
2. **`autolink` now defaults to `true`.** `normalizeBareLinks()` already
rewrites bare URLs into Markdown links before rendering, so both would
run. `message_content` opts out with `autolink: false` to keep current
behaviour exactly. The migration guide argues for dropping the
pre-processor instead — a better fix, but a behavioural change that
belongs in its own PR.
3. **`gpt_markdown.dart` now re-exports `markdown_config.dart`**, making
two direct imports redundant. `flutter analyze` reports `No issues
found!` on 1.1.6 and flags both on 1.2.1, so these warnings are new, not
pre-existing.

**Deliberately out of scope.** The three non-message call sites now
autolink bare URLs, since only `message_content` has a pre-processor to
collide with. Custom inline components (`_MentionMd`, `CustomEmojiMd`,
`_ChannelLinkMd`) could additionally declare `allScopesExceptLinkLabel`
— 1.2.0 offers it as the fix for a `WidgetSpan` chip going blank inside
a link label on iOS — but current behaviour is unchanged without it, so
that stays a separate change.

### Related issue

Fixes block#5257

Duplicate scan: searched `gpt_markdown`, `inline code mobile`,
`highlightBuilder` and `InlineCodeStyle` across both PRs and issues. No
open PR touches inline code styling. block#6135 (link labels) and block#6166 (text
selection) also touch mobile Markdown but address different defects.

### Testing

Full gate, `just ci` — exit 0:

| Stage | Result |
|---|---|
| Rust (33 suites) | 4768 passed, 0 failed |
| Desktop | 5799 passed, 0 failed |
| Mobile | **2011 passed**, 0 failed |
| `flutter analyze` | `No issues found!` |
| Desktop + web build | ok |

Run on the branch with `main` merged in, so these numbers match what CI
builds.

**New regression test** — `renders inline code in the app code style`.
It resolves the `CodeTextSpan` the package tags inline code with, which
carries both the resolved `TextStyle` and the colours the chip behind it
is painted with, so face, size, ink, fill and outline are all asserted
rather than a widget's presence. It is negative-controlled: reverting
only the theme declaration fails it with

```text
Expected: a numeric value within <0.001> of <13.0>
  Actual: <14.1>
```

and dropping the declaration entirely falls back to
`packages/gpt_markdown/JetBrainsMono` — so the test measures the real
thing, and it would catch a future regression that silently drops the
theme extension.

The test passes `baseStyle: messageBodyTextStyle`, the style the message
surfaces actually use; the widget's own fallback is the smaller
`bodyMedium`, which would move the expected size.

The test finds paragraphs with `find.byWidgetPredicate((widget) =>
widget is RichText)`, not `find.byType(RichText)`: inline code renders
through `BidiRichText`, a `RichText` subclass, and `byType` matches
exact runtime types.

That is a hazard for any test that reads text back out of a paragraph,
and one landed after this branch was cut:
`message_content_custom_emoji_test.dart` arrived with block#6996 and its
`code keeps literal emoji while adjacent known tokens render` case reads
a code span through `find.byType(RichText)`. It passes on `main` and
fails on the merge result, which is what CI builds, so it went red only
once CI was authorized. It now uses the same predicate. The two other
`byType(RichText)` call sites — the rest of that file and
`message_author_meta_test.dart` — were re-run and pass: their content
carries no code span, so the exact type still matches. They were left
alone.

### Screenshots

Rendered through the real `MessageContent` widget with the app's own
fonts loaded, at 390pt wide, 3x DPR. Sample text: ``Set `BUZZ_RELAY_URL`
before launch, then run `just mobile-test` to verify.``

Before: bold Inter on a flat wash, no chip edge, and `just mobile-test`
breaks across the line with the wash simply ending. After: Geist Mono in
a bordered, rounded chip, and the wrapped fragment gets its own chip on
each line.

## Summary

Adds an independent deadline wakeup so held thread work dispatches after
its 10-second bound even when the relay loop is otherwise quiet. Fences
session ownership by generation so a worker returning after a fork
cannot make an older provider session claimable again.

This follows up on the two post-merge findings from
[block#7337](block#7337 (review)).

### Related issue

Follow-up to block#7337.

### Testing

- `cargo test -p buzz-acp`
- `cargo clippy -p buzz-acp --all-targets -- -D warnings`
- Pre-push file-size, differential Rust test, and desktop Tauri gates

No UI changes.

**Update Sep 4, 15:35:** Addressed both Codex review findings.
- Queue-cap eviction now prunes orphaned hold deadlines.
- An expired hold stays expired until a worker is successfully claimed.
- Hold timers remain disabled while every worker is busy; worker return
wakes dispatch directly.
- Added regressions for queue eviction and pool exhaustion.

Generated with Codex
