After https://gitea.com/gitea/runner/pulls/1304, logrus stayed only to forward logs from docker/cli and moby/go-archive. The runner used a small part of those: volume parsing, the build context tar, the `ssh://` connection and registry credentials. Own code that matches them replaces them, so logrus leaves the module graph. docker/cli stays for its logrus-free `opts` and `connhelper/ssh` packages.
Other dependencies that the standard library or existing ones cover go too: mergo, httprouter (replaced by `http.ServeMux`), retry-go, go-isatty, go-selinux, container-device-interface, gotest.tools and go-cmp (replaced by testify). The binary shrinks by 5%.
Behaviour differences:
1. An unreadable file in a build context is skipped with a warning, where go-archive left a truncated tar.
2. Build contexts no longer carry `security.capability` xattrs.
3. The cache and artifact servers answer HEAD on GET routes, and no longer redirect trailing slashes or answer OPTIONS.

Move the log calls in `internal` onto `logging`, and add what the process-wide logger setup and its tests need: `SetTextFormat` with a line filter for secret masking (replacing `report.MaskingFormatter`), `SetReportCaller`, `SetDefault` and `logtest.SetDefault`. After this only the `logging` package imports logrus.

Sends the OTLP metrics under [OpenTelemetry semantic convention](https://opentelemetry.io/docs/specs/semconv/) names where the runner's data matches the definition, like `cicd.worker.count`, `cicd.system.errors` and the `go.*` and `process.*` runtime metrics, and under `gitea.runner.*` otherwise. OTel dashboards then work without remapping, as they already do for the traces from https://gitea.com/gitea/runner/pulls/1206.
Adds a `gitea_runner_state` gauge (`busy`, `idle`, `unavailable`), and `/readyz` now fails once the runner shuts down.
**Breaking**
1. OTLP metric names, units, types and attribute values change, and the info and start time metrics move to resource attributes.
1. Prometheus `gitea_runner_client_errors_total` gains a `code` label, and `gitea_runner_job_total` counts jobs stopped by `runner.timeout` as `timeout` instead of `failure`.

Push the runner's Prometheus metrics to the OTLP endpoint next to the job traces, so both land in the same backend.
The `/metrics` registry is converted as the [Prometheus compatibility spec](https://opentelemetry.io/docs/specs/otel/compatibility/prometheus_and_openmetrics/) describes and sent through the existing gRPC-free client, so names stay unchanged and no second metrics stack is linked. Metrics are on by default and pushed every interval and once on shutdown, so ephemeral runners report too.
New standard variables, each `OTEL_EXPORTER_OTLP_*` one with `TRACES` and `METRICS` variants:
- `OTEL_METRICS_EXPORTER`, `none` turns metrics off
- `OTEL_METRIC_EXPORT_INTERVAL`, `OTEL_METRIC_EXPORT_TIMEOUT`
- `OTEL_EXPORTER_OTLP_TIMEOUT`, `OTEL_EXPORTER_OTLP_COMPRESSION`
- `OTEL_EXPORTER_OTLP_CERTIFICATE`, `OTEL_EXPORTER_OTLP_CLIENT_CERTIFICATE`, `OTEL_EXPORTER_OTLP_CLIENT_KEY`
