gallery-coverage fails on feat-cmux-next for every PR that touches webviews: #22986 added subagents/SubagentPaneFooter.tsx#SubagentPaneFooter without a gallery entry.

• subagents.gallery.ts covers it and adds an own-pane variant: the pane gets a subagent: reveal (as when the app opens a subagent's pane), shows that subagent's view under the Subagent of pill, and draws the read-only footer line naming the chat instead of the composer. The play fails if the composer is drawn.

Summary by cubic

Fixes gallery-coverage on feat-cmux-next by covering SubagentPaneFooter, which #22986 added without a gallery entry.

Adds an own-pane variant to the subagents gallery that opens a subagent's view read-only via a subagent: reveal, verifies the footer line naming the chat appears in place of the composer, and fails if the composer is drawn.

Written by scripts/ci/classify_failures.py (ci-failure-attribution.yml); signatures are its SIGNATURES table. A machine verdict is the runner's fault, not this PR's; yours means the failing file is one this PR changes, also red on main that main's latest full suite fails the same way, seen on other PRs that it failed on another pull request's run lately.

red: cmux-next checks (god files, concurrency, crash safety, l10n); no finished base run on eac59b5 to compare; do not merge until green; see lane-rules

Tour of ef1f447375 (run): no media. The tour did not run: only webview code changed (1 path(s)), which the gallery advisory run checks in Linux Chromium on the pull request (its artifact holds any captures); add the media-tour-mac label to tour it on a Mac.
