fix: restore live typing focus after Enter

[enaboapps]

Summary

• defer live text input focus restoration until React Native has committed the editable state
• clear stale native focus bookkeeping with a bounded blur/focus sequence
• cancel pending restoration across submissions, mode/session changes, and unmount
• preserve Enter delivery, success clearing, failure retention, and retry behavior

Closes #111

Validation

pm run validate (pass; Expo Doctor 21/21)

px expo config --type public (pass; version/config unchanged)

• focused Jest coverage for focus scheduling, cancellation, both Enter paths, failure/retry, and session lifecycle (pass)
• git diff --check (pass)

Physical testing

• Android/iOS software-keyboard and assistive-technology smoke checks remain pending; no automated real-input injection was performed.

Compatibility

• no protocol, BLE, command payload, storage, dependency, native configuration, or version changes

Focused tests passed: 3 suites, 31 tests.

Physical Android/iOS keyboard and assistive-technology checks remain pending as disclosed in the PR.
