Installs SkillClaw from the current repository checkout into a local virtualenv.

Examples:
  bash scripts/install_skillclaw.sh
  bash scripts/install_skillclaw.sh --venv-dir ~/.venvs/skillclaw --run-setup
  bash scripts/install_skillclaw.sh --extras all --run-setup --run-start

Default install command:
  python -m pip install -e ".[evolve,sharing,server]"

After install you can run:
  skillclaw setup
  skillclaw start

If you also plan to use the agent evolve server, install OpenClaw separately:
  npm install -g openclaw
