Introduce support for per-command model defaults in config.toml, overriding global default if set. Update GetModel to accept command name and prioritize: flag > command default > global default. Add example config file and adjust all commands to pass their name. Update tests accordingly.
- Handle errors from fmt.Scanln in cmd/edit.go and cmd/lint.go to prevent crashes on input failures, providing user feedback and preserving backups.
- Update .gitea/workflows/release.yml to use 'ubuntu-gitea' runner for CI consistency.
Introduce new `grokkit lint` command for automatic language detection,
linting, and AI-suggested fixes. Supports 9 languages including Go, Python,
JavaScript, TypeScript, Rust, Ruby, Java, C/C++, and Shell.
- Add cmd/lint.go for command implementation
- Create internal/linter package with detection and execution logic
- Update README.md with usage examples and workflows
- Enhance docs/ARCHITECTURE.md and docs/TROUBLESHOOTING.md
- Add comprehensive tests for linter functionality
