Fix archaeology workflow Python cache setup

[simongonzalezdc]

Summary

• points the scheduled archaeology workflow's actions/setup-python pip cache at setup.py, matching this repo's legacy package shape
• quotes $GITHUB_ENV in the project-name bootstrap step so the workflow passes actionlint cleanly

Why

The latest default-branch DevArch Archaeology Report failed before DevArch ran because setup-python could not find its default pip cache dependency files (requirements.txt or pyproject.toml). This repo currently has setup.py, so the cache dependency path needs to be explicit.

Fixes #34.

Verification

• actionlint .github/workflows/archaeology.yml
• git diff --check
• static assertion that setup.py exists and .github/workflows/archaeology.yml references it as cache-dependency-path

📝 Walkthrough

Walkthrough

Two targeted updates to the DevArch Archaeology Report workflow: the Python setup step now explicitly declares setup.py as a cache-dependency path to invalidate the Python cache when dependencies change, and the PROJECT_NAME environment variable export uses quoted syntax for the GitHub environment file reference.

Changes

GitHub Actions Workflow Configuration Fix

Layer / File(s)	Summary
Dependency caching and environment variable handling .github/workflows/archaeology.yml	Python setup step adds cache-dependency-path: setup.py to enable cache invalidation when dependencies change. PROJECT_NAME export to $GITHUB_ENV now uses quoted variable reference for correct shell interpretation.
