Usage: $(basename "$0") [SUBCOMMAND] [OPTIONS]

S7: Operator connect helpers — wire the owner's SaaS and channels.

Safety model: --dry-run is the default. Use --apply to perform mutations.
  --dry-run   Preview actions without executing (default)
  --apply     Execute mutations (prompts for credentials when needed)

Subcommands:
  status                          Show current connection status
  name [--dry-run|--apply]        Name / profile setup (sandbox rename guidance)
  channels [--target <ch>]        Connect messaging channels
                                  --target whatsapp|email|telegram
  square [--dry-run|--apply]      Connect Square (remote MCP)
  quickbooks [--dry-run|--apply]  Connect QuickBooks Online (local MCP)
  vagaro [--dry-run|--apply]      Connect Vagaro (REST + webhooks)
  all [--dry-run|--apply]         Walk all targets sequentially

Options:
  --help                          Show this help
  --dry-run                       Preview only (default)
  --apply                         Execute mutations
  --target <name>                 Target channel (for 'channels' subcommand)

Examples:
  $(basename "$0") status
  $(basename "$0") square --dry-run
  $(basename "$0") square --apply
  $(basename "$0") channels --target telegram --dry-run
  $(basename "$0") all --dry-run

State:
  Connection state is stored in .local/capability_state.json (gitignored).
  Fixtures under data/fixtures/setup/ are NOT modified.

Platform-first:
  All mutations use nemohermes / openshell. No parallel control API.
  Owner never receives terminal/Docker/nano instructions.
