docs: update Node.js to 24 LTS, switch to nvm + corepack

- Use nvm v0.40.4 + nvm install 24 (24.14.0 LTS) instead of nodesource
- Use corepack enable pnpm instead of npm install -g pnpm
- Add symlink step: ln -sf \$(nvm which current) /usr/local/bin/node so
  systemd service can reference a stable path
- Update ExecStart in innercontext-node.service: /usr/bin → /usr/local/bin
- Update Node.js version references in README.md (22 → 24 LTS)
