Flutter Release Readiness

Prepare a Flutter app for Android and iOS release: versioning, quality gate, signing guidance, store metadata, build commands, and CI/CD checklist.

Workflow

1. Run universal pre-release gate (both platforms must pass before continuing).
2. Run Android-specific checks.
3. Run iOS-specific checks.
4. Run quality validation — all three commands must pass.
5. Generate docs/release/release_checklist.md using templates/release_checklist.md.
6. Generate CI/CD templates if not present (from templates/github_workflows/).
7. Present final blockers list — do not execute release builds until user approves.

NEVER run flutter build release or publish commands without explicit user approval. NEVER commit signing credentials to source control.
