fix(setup): seed setuptools+wheel before editable install

[brandwe]

Summary

Python 3.12's venv module stopped seeding setuptools and wheel by default. The bare pip install -e ".[dev]" step in setup.sh fails because pip needs setuptools to build the editable install from pyproject.toml. Both attempts in the script (the .[dev] install + the bare . fallback) fail for the same reason, and both errors are silently swallowed by 2>/dev/null — leaving the venv with only pip installed and looking superficially "ready."

Reproduction

After setup.sh runs cleanly to completion, manually invoking the same install command surfaces the real error:

$ pip install -e ".[dev]"
ERROR: File "setup.py" or "setup.cfg" not found. Directory cannot be installed in editable mode: /path/to/repo
(A "pyproject.toml" file was found, but editable mode currently requires a setuptools-based build.)

The venv has pip but no setuptools or wheel.

Fix

Add pip install --quiet --upgrade pip setuptools wheel between venv creation and the editable install, in both places setup.sh creates a venv:

• Step 6 (Blueprint certificate prep, around line 866)
• Step 7 (main install + .env write, around line 1060)

Test plan

• Delete .venv/, run setup.sh end to end, confirm the editable install succeeds without manual intervention
• Confirm .venv/bin/pip list shows entrabot + setuptools + wheel after the script completes
