fix: setup UX improvements — adapter check, ENOENT, SQLite warning, VERSION, PATH docs

- setup validates adapter binary availability, prints install command if missing
- setup prints 'Config saved to <path> ✓' on success
- spawn ENOENT gives actionable error with which command
- SQLite ExperimentalWarning suppressed via NODE_OPTIONS
- bootstrap VERSION reads cli package.json (was reading util)
- bootstrap PATH guidance is shell-agnostic

Fixes #114
