chore(alpha): sync upstream main (7a12aff4)

[cursor]

What Changed

Merges official pingdotgg/t3code main into Alpha with merge ancestry preserved.

• Alpha base: 9eba6ba087dadbb45cd0d7da05f2711274f69f95
• Upstream main: 7a12aff471ffe2b22b9fee495b04b32c43f45a37
• Candidate merge: 8263953ffd178ac39072b9a3349b02b9477e19bb

Incoming upstream commits (2):

• d06f0ff10 fix(sqlite): retry failed statement preparations (fix(sqlite): retry failed statement preparations pingdotgg/t3code#10584)
• 7a12aff47 fix(mobile): scale Android controls with appearance text size (fix(mobile): scale Android controls with appearance text size pingdotgg/t3code#13356)

Why

Keeps Alpha current with upstream. Git merged without conflicts, and Alpha has no delta in any of the 32 incoming paths, so all 13 active or partial features in .alpha/features/ are classified unaffected. Feature records now point at 7a12aff4, and .alpha/reconciliation.jsonl has a journal entry with the local validation.

Local validation

• vp test run packages/shared/src/nodeSqliteClient.test.ts apps/mobile/src/lib/androidControlSizing.test.ts: 8 passed
• vp test run apps/server/src/persistence/: 26 files, 58 tests passed
• vp test run scripts/record-alpha-safe-sync.test.ts scripts/classify-alpha-sync.test.ts scripts/alpha-workflow-contract.test.ts: 11 passed
• Typecheck packages/shared and apps/mobile: passed
• vp check on incoming files: 0 errors; vp fmt --check on feature records: clean

Not verified locally: Android on-device text scaling behavior.

UI Changes

Upstream-only Android mobile sizing changes; no Alpha UI changes.

Checklist

• This PR is small and focused
• I explained what changed and why
• I included before/after screenshots for any UI changes (upstream change, not applicable)
• I included a video for animation/interaction changes (not applicable)
