Implement Render cloud integration with CLI and API support:
- render/lib/common.sh with provider primitives (auth, provision, SSH, upload)
- render/claude.sh for Claude Code deployment
- render/aider.sh for Aider deployment
- Updated manifest.json with Render cloud and 14 matrix entries
- Created README.md with usage documentation
Render offers a developer-first platform with free tier, Docker support,
and SSH access via render CLI. All scripts support OpenRouter integration.
