feat(desktop): PR-style file diffs in chat (#50731)
* feat(desktop): add Update now button to About panel

The About > Updates panel only surfaced "See what's new" when an update
was available, which just opens the changelog overlay — there was no way
to start the install directly from About. Add an "Update now" primary
button that opens the updates overlay (for apply progress) and kicks off
the install for the active target (backend in remote mode, else client).

* feat(desktop): PR-style file diffs in chat

Render write_file/edit_file/patch as a reviewable diff instead of raw
result JSON, closer to a Cursor/T3 per-edit review.

- Unified diff via FileDiffPanel: strip git file-header + @@ hunk noise,
  drop the +/- gutter, color by line with a 2px gutter accent, full-bleed
  to the card, transparent context lines, compact scroll height.
- Header shows filename + language icon + +N/-N stats; full path moves to
  a hover tooltip (no Edited verb, no ms).
- Treat the three file-edit tools uniformly (isFileEditTool); read diff
  from inline_diff or patch's diff field; suppress raw-arg detail.
- Reusable FileTypeIcon primitive sharing the code-block icon mapping
  (codiconForFilename), codicon fallback.
- Per-row scaffolding fade (not the group wrapper, which trapped child
  opacity); expanded edits stay full, collapsed fade; keyboard-only focus
  lift. Hide diff-less rehydrated creates that read as dupes.

* style(desktop): lead --dt-font-mono with bundled JetBrains Mono

Code/diff blocks preferred a system Cascadia Code before the bundled
JetBrains Mono, so they drifted from the terminal (which leads with
JetBrains Mono) on machines where Cascadia is installed. Reorder so every
mono surface uses the face we actually ship.

* feat(desktop): syntax-highlight inline diffs via Shiki

Unify the diff renderer onto the same Shiki path as code blocks: highlight
the marker-stripped change content in the file's language, then a per-line
transformer layers the add/remove tint + gutter accent on top. Falls back
to the plain color-only renderer when the language is unknown, over budget,
or while Shiki loads.

- shikiLanguageForFilename(): extension → bundled-language id (shared
  filename-token helper with codiconForFilename).
- code display:grid so full-width line tints don't double with newline
  nodes; theme surface stripped so context lines stay transparent.

* style(desktop): use github-dark-dimmed for inline diffs

The vivid github-dark-default tokens read harsh behind the add/remove
tint in dark mode; switch the diff's dark theme to GitHub's lower-contrast
dimmed palette. Light mode and code blocks are unchanged.

* style(desktop): dim code-block syntax theme + share with diffs

Apply github-dark-dimmed to code blocks too (not just inline diffs) and
export one shared SHIKI_THEME so the two highlighters can't drift. Lower
contrast reads easier at our small code size in dark mode.

* style(desktop): soften shiki token contrast in dark mode

github-dark-dimmed only dims the background, which the diff/code surfaces
strip — so the bright token foregrounds were unchanged. Pull saturation +
brightness back a touch (hues preserved) on .shiki in dark mode for both
code blocks and inline diffs.
