Fixes#3038
Users hit "command not found: moltbot" after install because docs only
reference `moltbot`, but package.json defines both `moltbot` and `clawdbot`
bins. Some install methods may expose only `clawdbot`.
Changes:
- Add "try clawdbot (compatibility shim)" fallback in 7 key docs
- README, install docs, getting started, troubleshooting
- Consistent messaging: try clawdbot first → then check PATH
- All links follow Mintlify root-relative convention
