Replace the upstream Windows/local-run README with a dev-focused one: how the
client redirection works (loader+agent+backend.txt), repo structure, building
and running the API in a container, the TLS cert SAN gotcha, the Gitea CI/CD
branch model (preprod:preprod / main:latest), the Prospect.Client.Config
switch+cert tool, and an up-to-date feature status.
