feat: Complete Rust rewrite replacing TypeScript implementation

- Rewrite entire codebase from TypeScript/Node.js to Rust
- Fix all 10 security vulnerabilities (3 CRITICAL, 4 HIGH, 3 MEDIUM):
  - Command injection eliminated via Command::arg() (no shell interpolation)
  - File permissions enforced: 0o600 files, 0o700 directories
  - Atomic PID locking via flock(2) (no TOCTOU race)
  - Chat ID validation on ALL update types including callbacks
  - Rate limiting via governor token-bucket (25 req/sec)
  - Safe JSON parsing (serde Result, no panics)
- Single binary (ctm) with clap subcommands: start, hook, status, doctor, setup
- Dependencies: tokio, teloxide 0.13, rusqlite, governor, nix, serde, clap
- Remove all TypeScript, Node.js, npm artifacts
- Add comprehensive docs: Architecture, Setup, Development, Security guides
- Add 6 ADRs documenting key architectural decisions
- Add GitHub Actions CI workflow (check, test, clippy, fmt, release builds)
- 13 unit tests passing across session, socket, formatting, injector, config
- Migrate git remote to DreamLab-AI/Claude-Code-Rust-Telegram
