ci: refactor workflows to use centralized commands

Replace direct dart commands with custom commands defined in commands.yaml.
This improves maintainability by centralizing command definitions and makes
it easier to update test/analysis/format configurations across all workflows.

- Add commands.yaml with format, analyze, and tests commands
- Update CI workflow to use setup-commands action
- Update release workflow to use setup-commands action
