Tighten installer/runtime consistency so users on Node 22.0-22.11 are blocked before install/runtime drift, with cleaner CLI guidance.
- Enforce Node >=22.12 in scripts/install.sh preflight checks
- Align installer messages to the same 22.12+ runtime floor
- Replace openclaw.mjs thrown version error with stderr+exit to avoid noisy stack traces
Surface a clear Node 22.12+ requirement before npm/install bootstrap work so users avoid misleading downstream errors.
- Add installer shell preflight to block active Node <22 and suggest NVM recovery commands
- Add openclaw.mjs runtime preflight for npm/npx usage with explicit Node version guidance
- Keep messaging actionable for both NVM and non-NVM environments
