Logan Johnson 6cf514ed90 fix(desktop): wrap message tables within the available pane (#7279)
## Summary
- Let Markdown tables use the available message width instead of their
maximum-content width, inheriting the renderer's existing
`wrap-anywhere` handling for long tokens and links.
- Top-align header cells as well as body cells. Give cells a `min-w-24`
readability floor so short labels do not collapse into one-letter
columns; retain the existing table-local scrollbar when many columns
genuinely cannot fit.
- Preserve semantic table markup, links, inline code, and surrounding
message layout. Add three browser regressions through the real message
renderer (channel, narrow thread, and many-column overflow).

### Testing
Original production candidate:
`4427f2e6f9ef85a01a267fe9eabd1cf13cacfb78`; base:
`7a9a5233d9d755e715be0c585cf7850e935d28cf`.

- `pnpm -C desktop check` — passed.
- `pnpm -C desktop test` — 6,110 passed, none skipped.
- `pnpm -C desktop typecheck` — passed.
- `BUZZ_PROTECTED_BUILD_OUTPUT=<isolated-production-directory> pnpm -C
desktop build` — passed.
- `pnpm -C desktop build:e2e --outDir <isolated-candidate-directory>` —
passed.
- `just file-size-check` and `git diff --check` — passed.
- Chromium / mock Tauri bridge: all 3 new Playwright tests passed
against the fixed candidate build. Both wrapping tests fail on the
unchanged base build, while the overflow-fallback test passes. Each
browser run used a unique output directory and a non-reused local server
pinned to its build directory.
- At 883px channel message width: table scroll width **1,395 → 883px**.
At 292px thread message width: **1,395 → 292px**. All cells top-aligned;
long tokens/URLs wrap, link destinations and code text remain intact,
short labels stay on one line, and document width remains 1,280px.
- Focused fresh-frame review checked actual before/after screenshots and
the complete diff. It caught one-letter label wrapping in an early
width-only candidate; the final cell-width floor and regression
assertion address that finding.

Limitations: native Tauri/WebKit and relay-backed integration were not
exercised for this CSS-only delta. Repository-wide `just ci` was
attempted but exceeded the local command budget during unrelated Rust
compilation; it is **not** reported green. The full affected TypeScript
package gates above passed on the exact candidate. Production/E2E builds
retain existing chunk-size and mixed static/dynamic import warnings.

Before/after screenshots are posted below using the repository's
screenshot publication script. No merge, production installation, or
runtime restart is requested.


### CI-driven test-only follow-up
Current head: `925d964b6cf31ba704d74baf73769110774b2789`.

Smoke shard 3 exposed an older test in `messaging.spec.ts:457` that
still required three columns of ordinary prose to overflow horizontally
([failure
log](https://github.com/block/buzz/actions/runs/33771325404/job/100702242706)).
This expectation contradicts the intended wrapping change. Updated its
name and assertion to require containment; the separate many-column
local-scroll test is unchanged. No production code or harness settings
changed in this follow-up.

- Affected browser validation: **4/4 passed** (updated existing
prose/narrow table case plus the three new channel/thread/overflow
cases).
- Reused the immutable `4427f2e6` E2E build on a fresh non-reused
server; production source is unchanged at the current head. The
package/build checks above remain evidence for that unchanged production
tree, not a claim of rerunning the full suite at the new SHA.
- Targeted Biome check, file-size gate, and `git diff --check` passed.
- Current-head CI:
https://github.com/block/buzz/actions/runs/33773490446
- Prior unrelated Bestie baseline failure and reproduction:
https://github.com/block/buzz/pull/7279#issuecomment-5528077181
- Security authorization and review must target the **current** head,
not the old screenshot/build SHA. A Block organization member must
comment exactly `@buzz-security-review
925d964b6cf31ba704d74baf73769110774b2789`.
