Initial release of CHORUS Development Images

This commit establishes the foundation for language-specific development
container images used by CHORUS autonomous agents.

Features:
- Multi-stage Dockerfile with 7 layered images
- Base Debian Bookworm image with common tools
- Language-specific images: Rust, Go, Python, Node.js, Java, C/C++
- Standardized /workspace/{input,data,output} structure
- Automated CI/CD pipeline for weekly security updates
- Comprehensive test suite for all images
- Full documentation (README, USAGE, MAINTENANCE)

Images available:
- chorus/base:1.0.0 (~200MB)
- chorus/rust-dev:1.0.0 (~1.2GB)
- chorus/go-dev:1.0.0 (~600MB)
- chorus/python-dev:1.0.0 (~800MB)
- chorus/node-dev:1.0.0 (~700MB)
- chorus/java-dev:1.0.0 (~1.5GB)
- chorus/cpp-dev:1.0.0 (~900MB)
