Taylor Ho 092c6a7277 fix(markdown): align mention chip wrapping (#7501)
**Category:** fix
**User Impact:** Human and agent mentions now break across lines with
the same cloned chip treatment as repository and permalink chips while
preserving the conversation text rhythm.

**Problem:** Profile-backed rendered mentions sat inside an
`inline-flex` popover trigger, unlike entity chips, so the wrapper
interfered with true inline fragmentation. The browser-layout test
measured text-range rows rather than the painted chip rectangles,
allowing touching decorations to pass as “separate” fragments.

**Solution:** Keep the profile trigger interactive but override its
layout to true `inline`, then give mention fragments 18px computed
leading inside the message’s 20px prose rhythm. Chromium paints each
fragment at 17px and advances it by 20px, leaving a visible gap between
cloned rounded rectangles. The browser test now measures the chip’s own
`getClientRects()` and asserts fragment count, height, gap, and step;
entity links retain their existing 22px leading.

<summary>File changes</summary>

**desktop/src/features/profile/ui/UserProfilePopover.tsx**
Allows inline consumers to override the trigger wrapper’s layout without
changing other profile-popover call sites.

**desktop/src/shared/styles/globals/markdown.css**
Keeps one shared wrapping-chip mechanic and gives mention decorations
enough room to separate visibly within 20px prose.

**desktop/src/shared/ui/markdown.test.mjs**
Pins both rendered mentions and entity links to the shared wrapping-chip
contract.

**desktop/src/shared/ui/markdown/MarkdownMention.tsx**
Makes the profile-popover trigger truly inline so the nested mention
chip can fragment with surrounding prose.

**desktop/src/shared/ui/mentionChip.ts**
Keeps `wrapping-inline-chip` as the single contract for fragmenting
decorated chips.

**desktop/tests/e2e/mentions.spec.ts**
Measures the painted chip rectangles, requires a positive fragment gap,
and verifies the inline trigger remains mouse- and keyboard-operable.

**desktop/tests/e2e/navigation.spec.ts**
Keeps a wrapped repository chip as the control, asserting its existing
22px line height and fragment advance.

## Reproduction steps

1. Open a channel in Buzz Desktop using dark theme.
2. Send a message containing a human mention and another containing an
agent mention; both chips should remain aligned with adjacent text on a
20px line.
3. Render a collision-qualified mention in a narrow message width; it
should break into separately decorated fragments exactly like another
wrapping chip, while each fragment follows the 20px prose rhythm.
4. Render a long repository or permalink chip in the same constrained
width; it should retain its roomier 22px fragment spacing.

## Screenshot

The dark-theme production renderer shows the real qualified label (`bob
(npub1hv3…tpuc)`) at an 8rem width. The two lines now paint as visibly
separate rounded fragments rather than one continuous rectangle.

## Validation

At commit `2b063e1b4ade30e11f1616269ad4ba4190366885`:

- Pre-push desktop gates — file-size check, Biome/checks, typecheck, and
6,483 unit tests passed
- `pnpm --dir desktop build` — passed
- Focused Playwright coverage for single-line agent mention, single-line
human mention, wrapped qualified mention including keyboard profile
activation, and timeline mention click — 4 passed
- `git diff --check` — passed
