ci: replace release-that action with semantic-release

- Update workflow triggers to support scheduled daily releases at UTC midnight
- Add workflow_dispatch for manual release triggering
- Add conditional logic to only run release on main branch pushes, schedules, or manual triggers
- Replace rlespinasse/release-that@v1 with cycjimmy/semantic-release-action@v4
- Switch from custom GH_TOKEN to standard GITHUB_TOKEN
- Create .releaserc.json with minimal semantic-release configuration
- Automatically analyzes conventional commits and generates releases
- Enables once-daily release cadence with unpublished commit detection
