* feat(waitlist): capture OpenCode Connect signups via beta-signup API (closes#87)
The 'OpenCode Connect — Coming Soon' card only opened a raw mailto: link,
so waitlist signups existed solely as loose emails in the support inbox
with no backend capture.
- POST the signup to https://opencode.agentlabs.cc/api/beta-signup
(OpenCodeMobileSite route -> Brevo list) tagged with
source: "opencode-connect-waitlist". The route ignores unknown fields
today, so the tag is forward-compatible.
- Pure payload/validation/fallback logic lives in src/lib/waitlist.ts
(no react-native imports, dependency-injected fetch, AbortController
timeout like diagnostics.ts) with node --test coverage.
- Graceful degradation: transport failures and 5xx fall back to the old
mailto: path so the signup still reaches the inbox; 4xx asks the user
to fix their email. Success shows an inline confirmation state.

* fix(waitlist): handle mailto fallback failure, name 502 in fallback test
Review findings: Linking.openURL was fire-and-forget, so a device with
no mail app failed the recovery path silently — await it and alert with
a manual instruction instead. Test title now names 502 (Brevo failure)
as an explicit fallback case.
