P1: Fix TestFlight deployment — add LendairApp executable target,
use xcodebuild archive/export instead of swift build for IPA
P2: Fix swift-format — use built-in 'swift format lint' (Swift 5.6+)
instead of external 'swift-format' binary
P3: Create missing index.html for Vite build entry point
P3: Update vercel-action from v30 to v25 (better maintained)
The stale-run detector flagged the same Code Reviewer ghost run
(14acabf9, FRE-4695) for the ~11th time. Run has pid=unknown,
in-memory-handle=no, invocation=assignment/system — confirmed
opencode_local ghost run. Documented in Code Reviewer's AGENTS.md
as expected behavior. Root fixes tracked in FRE-4990 and FRE-5042.
