Bug: uv pip install will fail in CI without a virtual environment

The JS workflow template (codeflash-optimize-js.yaml) sets up Python and uv but never creates a virtual environment:

- name: 🐍 Setup Python
  uses: actions/setup-python@v5
- name: 📦 Setup uv
  uses: astral-sh/setup-uv@v4
...
- name: 📥 Install Codeflash
  run: uv pip install codeflash   # ← will fail: "No virtual environment found"

uv pip install requires either an active virtual environment or the --system flag. The original uv tool install codeflash did not have this restriction — it installs a tool globally and works without any venv.

Without a venv, this step will fail with:

error: No virtual environment found; run `uv venv` to create one or pass `--system` to install into a non-virtual environment

The fix is one of:

• Use uv pip install --system codeflash — installs into the system Python set up by setup-python@v5
• Add a uv venv && uv pip install codeflash step
