Trimmed AI-flavored structure from docs/contribute.md and CONTRIBUTING.md:
removed the Discord vs Documentation comparison table, merged the High
Priority / Also Welcome buckets into a single What is Most Useful list,
dropped the duplicate closing exhortation that appeared at the bottom
of both files.
Added a Pull Request Guidelines section to both pages covering:
commit prefix convention (docs/fix/feat/chore, no subscope), one
logical change per PR, hardware-verified claims, source attribution
for non-obvious claims, cross-reference over duplication, and PR title
matching the commit subject.
- Add CONTRIBUTING.md with detailed contribution guide
- Add docs/contribute.md page in documentation site
- Update README.md to emphasize community collaboration
- Remove internal project files from repository (DEV.md, PROJECT_STATUS.md, etc.)
- Update .gitignore to exclude internal working files
