Rename CLI from 'nexadb' to 'nexa' - Clean separation

BREAKING CHANGE: CLI binary renamed from 'nexadb' to 'nexa'
Benefits:
- No command conflicts: 'nexadb' for server, 'nexa' for interactive CLI
- Clean UX: Single installation gives both commands
- Professional: Like mysql (mysqld + mysql client)
Changes:
1. Rust CLI:
   - Binary name: nexadb → nexa
   - Command name: nexadb → nexa
   - Prompt: nexadb> → nexa>
   - Help text updated
2. Build & CI/CD:
   - build.sh outputs nexa-{platform} binaries
   - GitHub Actions builds nexa-{platform} artifacts
   - All 5 platforms supported (macOS Intel/ARM, Linux x86/ARM, Windows)
3. Linux Installation:
   - install.sh now downloads nexa binary from GitHub releases
   - Auto-detects architecture (x86_64/aarch64)
   - Installs to ~/.local/bin/nexa
   - Updated help output to show 'nexa -u root -p'
4. Docker:
   - Dockerfile downloads nexa binary (architecture-aware)
   - Available at /usr/local/bin/nexa inside container
   - docker exec -it <container> nexa -u root -p
User Experience:
  brew install nexadb          # or curl install.sh
  nexadb start                 # Start server
  nexa -u root -p              # Interactive CLI
