Rename the entire project from "Validatrix" to "Nimcheck" in README.md, Makefile, LESSONS_LEARNED.md, and all source references; add initial Gitea CI workflow with lint, test, and build jobs for Nim 2.0.0; expand .gitignore with comprehensive patterns for Nim, Python, editor, environment, and temporary files; add CONTRIBUTING.md and LICENSE (MIT) files to establish project governance and licensing.
README:
- Expand building section with Makefile, nimble, and manual targets
- Add CLI usage examples for all commands (stdin, detect, version)
- Expand API reference with all public functions (validateSourceJson, reportFile, etc.)
- Add JSON output documentation
- Expand development section with project tree and language-adding guide
- Add versioning and prerequisites sections
LESSONS_LEARNED:
- Add Class 9: Missing .gitignore -- build artifact tracking risk
- Add Class 10: Repository directory name mismatch
- Renumber all sections 11-16 to accommodate new entries
- Update test count from 256 to 250+
- Update total bug counts
Establish the Validatrix source code validation framework in Nim, including core detection, tokenization, and validation infrastructure for 10 languages (bash, HTML, JavaScript, Jinja, JSON, Nim, PHP, Python, TOML, YAML). The initial commit introduces the main validatrix.nim entry point with public API (validateSource, validateFile, inspectSource), a comprehensive test suite with per-language test files, build configuration via Makefile and .nimble, detailed LESSONS_LEARNED.md documenting 14 bug classes found during development, and a .gitignore excluding compiled binaries, logs, and build artifacts. The detector module provides extension-to-flavor mapping for 40+ file extensions and content-based language detection, while the debug module supports conditional compilation with -d:validatrixDebug for detailed tokenization logging.
