Follow-up to #200 and #201, which gate the welcome buttons and the run-mode
dropdown on whether the CLI is actually installed. Four corrections:
1. #200 also DELETED the Cloudflare Tunnel welcome button and the QR widget
outright. Its rationale is right (offering a tunnel where cloudflared is not
installed is a bad default) but the conclusion overshoots: the welcome QR is
the whole scan-to-connect-from-your-phone flow, and deleting it left a large
block of live tunnel code in settings-ui.js driving elements that no longer
existed. Both are restored and the button is gated on cloudflared, which is
what the stated rationale actually asks for. New cloudflared-resolver.ts
mirrors the CLI resolvers, and TunnelManager now shares its search path so
the button and the spawn can never disagree about where cloudflared lives.
2. Antigravity was missing from the run-mode gating, the one run mode LEAST
likely to be installed. It slipped past because #201 predates it. Covered
now, plus a static test that fails if a sixth mode reaches the dropdown
without being gated, so the next one cannot slip the same way.
3. The per-surface fetches are replaced by the injected availability object
already used for the Codex settings tab, so the codebase has one mechanism
rather than two. The status routes buy nothing as a gating source: every
resolver memoizes its PATH probe server-side, so a fetch is exactly as stale
as an injected value while costing a round trip every time the dropdown opens
and leaving the welcome buttons to flicker in after paint. The routes
themselves stay, including the /api/claude/status that #200 adds.
4. Unknown availability now reads as AVAILABLE for run buttons. Both PRs hid the
button on a failed fetch, so a blip left a working install with nothing to
click; a genuinely missing CLI only ever produced an error toast. The Codex
settings TAB keeps the opposite default, since hiding it costs nothing.
The dropdown query is also scoped to the menu: `.run-mode-option` is the class
the saved-dashboard and history rows use too, and a document-wide querySelector
would have found whichever came first in the DOM.
Fixes a latent environment-sensitivity in 816d900 while here: the index-title
test asserted the template was untouched apart from the title, which held only
on a machine with no codex installed.
Verified end-to-end against a real server on an isolated instance+socket, with
Playwright: gemini/codex hidden and claude/opencode/antigravity/shell shown,
matching this host, tunnel button back, Codex settings tab still hidden, no
console errors. Full test:ci sweep green (3902 tests).
