chore: restore pubspec constraints and fix release workflow install

[Eimen2018]

Summary

• restore pubspec.yaml constraints to avoid unintended dependency floor downgrades
• pin semantic-release extra plugins in release workflow to versions compatible with cycjimmy/semantic-release-action@v3

Why

Publishing was failing before pub publish due npm peer resolution in the release step:

• action v3 runs semantic-release v19
• unpinned @semantic-release/exec resolved to v7 (requires semantic-release >=24.1)
• result: npm install failed with ERESOLVE

Changes

• pubspec.yaml
  • restore higher constraints for path, recase, meta, stacked_shared, dart_style, code_builder, collection, json_annotation, build_runner, test, json_serializable
• .github/workflows/release.yml
  • pin:
    • @semantic-release/exec@6
    • @semantic-release/git@10
    • @semantic-release/changelog@6

Validation

• flutter pub get
• dart analyze (infos only)
• dart test -r compact
• local npm compatibility check: semantic-release@19 + pinned plugins installs successfully
