Eliminate .bak file backups from edit, docs, lint, testgen, and agent commands to simplify safety features, relying on previews and confirmations instead. Update README, architecture docs, troubleshooting, and TODOs to reflect changes. Adjust tests to remove backup assertions.
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
