- Fix grammar.js TypeScript errors by correcting optional field usage
- Update .yamlignore to use more robust glob pattern (**/node_modules/**)
- Remove hard-coded test count from README.md for maintainability
- Fix shellcheck directive format (add space after #) in all test specs
- Fix typos throughout test specifications:
- 'can not' → 'cannot'
- 'expantion' → 'expansion'
- 'singnal' → 'signal'
- 'It mean' → 'It means'
- Update CODE_OF_CONDUCT.md HTTP links to HTTPS
- Update tree-sitter parse command to use --scope instead of --language
- Add comments to .mega-linter.yml explaining disabled linters
All grammar tests still pass (61/61) and the parser functions correctly
with the updated tree-sitter CLI v0.25.0.
