Merge PR #6: Revert to shell script implementation

[Copilot]

📝 Description

Reverts project from Go-based CLI to shell script implementation, restoring pre-Go-CLI architecture.

Key Changes:

• Removed: Go source (src/), go.mod, go.sum, Go-based TUI
• Added: Shell scripts for installation, management, and server operations
  • install.sh - Installation with interactive/auto modes
  • manage.sh - Server management interface
  • scripts/ - 11 utility scripts (bootstrap, update, cleanup, auto-update, tmux, etc.)
• Updated: All documentation to reflect shell script usage
• Modified: .gitignore, config paths, override structure

Architecture Change:

# Old: Go binary with TUI
csm install --servers 5

# New: Shell scripts
bash install.sh --auto --servers 5
./manage.sh
