woodpecker main.yaml: A+B combined CI dependency speedup — test-UTs-n-ITs swaps image from python:3.13-slim to gitea.earthmanrpg.me/discoman/python-tdd-ci:latest (same image as the two FT steps) so all 3 steps inherit the requirements.dev.txt deps Dockerfile.ci already pre-installs; all 3 steps switch pip install -r requirements.txt → pip install -r requirements.dev.txt so the install collapses to ~5-10s of "already satisfied" verification per step (vs ~30-60s of unpinned PyPI resolver+download against requirements.txt); ~3-5 min saved per pipeline run; drift safety net preserved — pip still installs deltas if requirements.dev.txt is ahead of the image, so a stale image doesn't break CI, it just runs slower until the image is rebuilt + pushed
