Restructure the script embedded in the scoped sync workflow into testable
functions, fix the invalid `exit 0` (now a successful run with a visible
warning when Gitea returns an invalid push mirror list) and report errors as
`ERROR: <message>` with exit code 1. Zero, several or malformed GitHub mirrors
still fail.
Add pytest-based offline tests (workflow YAML, embedded Python, credential and
mirror parsing, sync flow against a fake API) that run in a virtual
environment, and a validation workflow that runs them on pull requests and
pushes to main. Remove the manual tests/test_.ps1 probe and the duplicate
src/ copy of the workflow. Update the README and record the decisions for
tasks 1 and 3 in MIL-001.
