chore: bump Flutter pin 3.44.0 → 3.44.1 (CI + docs)

[timbortnik]

Summary

Local SDK was updated to Flutter 3.44.1 / Dart 3.12.1. This bumps the project pin to
match.

Patch bump — no breaking changes:

• Deps all up-to-date and resolvable (flutter pub outdated)
• SDK constraint ^3.10.4 still satisfied (Dart 3.12.1)
• Built-in-Kotlin / KGP setup unchanged (no plugins added)

Changes

• CI: flutter-version: '3.44.1' in test.yml, release.yml, codeql-default.yml
• CLAUDE.md: version references + history note (3.44.0 → 3.44.1)

Verification

Check	Result
make analyze	No issues found
make test-dart	115 passed
make test-kotlin	BUILD SUCCESSFUL
make debug	APK built (exit 0)

The benign Applying the Kotlin Android Plugin (KGP) was unsuccessful warning during the
build is expected under AGP-9 built-in Kotlin (documented in CLAUDE.md) — not a regression.
