chore: remove legacy moltbot/clawdbot compatibility

What:
- drop MOLTBOT_* and CLAWDBOT_* env wiring from HM + wrappers
- update gateway log-dir patch to target current upstream logger.ts
- update config options generator to require OpenClawSchema only
- update hello-world plugin example env var + module path
- rename RFC filename to remove moltbot naming

Why:
- upstream is OpenClaw; keep nix-openclaw opinionated + clean

Tests:
- bash -n scripts/update-pins.sh
