* feat(ci): improve linting configuration for instruction files
- Add GitHub-flavored Markdown support with remark-gfm
- Create generic Vale config (.vale-instructions.ini) for instruction files
- Use pattern-based file inclusion instead of explicit file lists
- Mount repository to /workdir in remark-lint container to preserve node_modules
Changes:
- Add remark-gfm to .ci/remark-lint/package.json
- Create .remarkrc.yaml at repository root for instruction files
- Update content/.remarkrc.yaml to include remark-gfm
- Create .vale-instructions.ini for generic writing rules
- Update compose.yaml: mount repo to /workdir (preserves /app/node_modules)
- Update lefthook.yml: use glob patterns for uppercase .md files and .github/**/*.md
- Update DOCS-CONTRIBUTING.md: remove empty CONTRIBUTING.md directory reference
Benefits:
- Automatic inclusion of new instruction files without config updates
- Pattern matching for uppercase .md files (DOCS-*.md, CLAUDE.md, etc.)
- Coverage for .github/, .claude/, api-docs/ directories
- GFM features: tables, task lists, strikethrough, autolinks, footnotes
- Separate linting rules for instruction files vs product documentation
feat(lint): separate remark-lint auto-fix for instructions vs report-only for content
- Split lint-markdown into two hooks:
- lint-markdown-instructions: Auto-fixes README, DOCS-*.md, .github/**, .claude/**
- lint-markdown-content: Reports issues in content/**, api-docs/** without modifying
- Changed remark-lint volume mount from read_only: true to read_only: false
- Instruction files now behave like Prettier (auto-fix + stage)
- Content files report errors and block commits until manually fixed
* chore(instructions): Add content/shared details, husky/lefthook updates
