1. Restructures the README into installation, quickstart, deployment, configuration, jobs and operation, and shortens it to user-facing prose. Option details are left to `config.example.yaml` and `docs/`, existing heading anchors are kept where possible. 2. FreeBSD builds used the Docker stub, so `docker://` labels, services and Docker actions failed there. The Docker code works on FreeBSD against a remote daemon, so it is enabled, and host jobs report `runner.os` as `FreeBSD`. 3. `make build` on Windows now writes `gitea-runner.exe`, taking the suffix from `go env GOEXE`.
