fix: reduce idle runner polling by default

Raise the default idle fetch backoff ceiling to reduce steady-state FetchTask traffic from idle runner fleets while keeping the value configurable for installations that need faster idle polling.

 Mount a volume on `/data` if you want the registration file and optional config to survive container recreation (see [scripts/run.sh](scripts/run.sh)).
 
-> **`/data` does not hold the image cache.** It is the runner's working directory and contains only the `.runner` registration file and, optionally, your config file. Images pulled for jobs live in the *Docker daemon's* data root, which for the `dind` flavours is inside the container (`/var/lib/docker`, or `/home/rootless/.local/share/docker` for `dind-rootless`). To keep the image cache across restarts, give that path its own volume as well — otherwise every new container re-pulls the job images. With the `basic` flavour the images live on whichever daemon you point the runner at, so there is nothing extra to persist.
-
 ### Image flavours
 
 The image is published in three flavours, all built from the single multi-stage [Dockerfile](Dockerfile) in this repository. They differ only in how a Docker daemon is made available to the jobs the runner executes; the `gitea-runner` binary inside them is identical.
@@ -123,8 +121,6 @@ Two processes have to run side by side here (the Docker daemon and the runner),
 
 Same idea as `dind`, but built on `docker:dind-rootless` so the bundled daemon and the runner run as an unprivileged user (`rootless`, UID 1000) rather than `root`. `DOCKER_HOST` is preset to `unix:///run/user/1000/docker.sock` so the runner talks to the rootless daemon. This reduces the blast radius compared to the privileged `dind` flavour, but rootless Docker carries the usual rootless limitations (networking, cgroups, storage drivers, and some operations that need additional host configuration such as `/etc/subuid` / `/etc/subgid` mappings and unprivileged user-namespace support).
 
-> **The UID is fixed at 1000.** It comes from the `rootless` user baked into the upstream `docker:dind-rootless` base image, and the bundled daemon always listens on `/run/user/1000/docker.sock` inside the container, so running this flavour as a different user (`--user 1001`) does not work. If you need the runner to talk to a *host* rootless daemon that runs under some other UID, use the `basic` flavour instead and bind-mount that daemon's socket (see [examples/vm/rootless-docker.md](examples/vm/rootless-docker.md)); pointing `DOCKER_HOST` at a host socket from inside `dind-rootless` will not work. Changing the UID otherwise means rebuilding the image from a base with a different `rootless` user.
-
 > **Note on Podman:** these images target the Docker daemon. The bundled `dind`/`dind-rootless` daemons are `dockerd`, not Podman, and the `basic` flavour expects a Docker-compatible socket. Running them under rootless Podman is not a supported configuration, though pointing the `basic` flavour at a Podman socket that emulates the Docker API may work for some workloads.

+If you omit `-c`, built-in defaults apply (same as an empty YAML document). A small set of **deprecated** environment variables can still override parts of that default config, but **only when no `-c` path was given**; they are ignored if you use a config file:
 
-Earlier releases let a small set of environment variables (`GITEA_DEBUG`, `GITEA_TRACE`, `GITEA_RUNNER_CAPACITY`, `GITEA_RUNNER_FILE`, `GITEA_RUNNER_ENVIRON`, `GITEA_RUNNER_ENV_FILE`) override parts of the default config. Those overrides have been removed — use a YAML config file for all settings instead. For the Docker images, the entrypoint still understands a separate set of variables (such as `RUNNER_STATE_FILE`); see [scripts/run.sh](scripts/run.sh) and the container documentation below.
-
-### Labels
-
-Labels decide **which jobs a runner accepts** and **how it runs them**. A job's `runs-on` is matched against the runner's label names; the first match wins and selects the execution environment for that job.
-
-A label is written as:
-
-```text
-<name>[:<schema>[:<args>]]
-```
-
-| Part | Meaning |
+| Variable | Effect |
 | --- | --- |
-| `name` | The name a workflow refers to in `runs-on`, e.g. `ubuntu-latest`. |
-| `schema` | Either `docker` or `host`. Defaults to `host` when omitted. |
-| `args` | Only used by the `docker` schema: the image to run the job in. |
+| `GITEA_DEBUG` | If true, sets log level to `debug` |
+| `GITEA_TRACE` | If true, sets log level to `trace` |
+| `GITEA_RUNNER_CAPACITY` | Concurrent jobs (integer) |
+| `GITEA_RUNNER_FILE` | Registration state file path (default `.runner`) |
+| `GITEA_RUNNER_ENVIRON` | Extra job env vars as comma-separated `KEY:VALUE` pairs |
+| `GITEA_RUNNER_ENV_FILE` | Path to an env file merged into job env (same idea as `runner.env_file` in YAML) |
 
-Two schemas are supported:
-
-- **`docker://<image>`** — the job runs inside a container created from `<image>`:
-
-  ```text
-  ubuntu-latest:docker://docker.gitea.com/runner-images:ubuntu-latest
-  ```
-
-- **`host`** — the job's steps run directly on the machine the runner is on, using the tools installed there:
-
-  ```text
-  macos:host
-  ```
-
-So with the labels
-
-```text
-ubuntu-latest:docker://docker.gitea.com/runner-images:ubuntu-latest,macos:host
-```
-
-a workflow with `runs-on: ubuntu-latest` is executed in the `runner-images:ubuntu-latest` container, and one with `runs-on: macos` is executed directly on the host.
-
-Names may themselves contain a colon (for example `pool:e57e18d4-10d4-406f-93bf-60f127221bdd`); only `host` and `docker` are treated as schemas.
-
-If a job's `runs-on` matches none of the runner's labels, the job still runs, in the default `docker.gitea.com/runner-images:ubuntu-latest` image. Images maintained for this purpose are listed at [gitea/runner-images](https://gitea.com/gitea/runner-images).
-
-Labels are chosen at registration time (`--labels`, or the interactive prompt) and can be changed afterwards by editing `runner.labels` in the config file, or in the Gitea UI under the runner's settings.
+Prefer a YAML file for all settings.
 
 #### Registration vs config labels
 
 If `runner.labels` is set in the YAML file, those labels are used during `register` and the `--labels` CLI flag is ignored.
 
-The `daemon` command also accepts `--labels` (which defaults to the `GITEA_RUNNER_LABELS` environment variable), so the labels of an already registered runner can be changed without deleting its registration file. The most explicit source wins:
-
-```
---labels / GITEA_RUNNER_LABELS   >   runner.labels in the config file   >   labels in the .runner file
-```
-
-Whenever the resulting labels differ from the ones in the registration file, they are written back to it and re-declared to the Gitea instance on startup.
-
-> **Note:** A runner that only exposes `host` labels still needs access to a Docker daemon (e.g. a mounted `/var/run/docker.sock`) whenever a job uses a `docker://` action or a service container. `host` labels only change where the job's own steps run; container-based steps and actions are still executed with Docker.
-
 #### Caching (`actions/cache`)
 
 Each runner starts its own cache server automatically. Cache entries are local to that runner — runners do not share a cache by default.

-# Running the runner as a systemd service
-
-[`gitea-runner.service`](./gitea-runner.service) is an example unit for running
-the runner as a background service on a systemd host.
-
-## Setup
-
-1. Install the `gitea-runner` binary (e.g. to `/usr/local/bin/gitea-runner`).
-2. Create a dedicated user and working directory:
-
-   ```bash
-   sudo useradd --system --home-dir /var/lib/gitea-runner --create-home gitea-runner
-   ```
-
-3. Generate a config and register the runner (as the service user), so the
-   `.runner` file ends up in the working directory:
-
-   ```bash
-   sudo -u gitea-runner gitea-runner generate-config > /etc/gitea-runner/config.yaml
-   cd /var/lib/gitea-runner
-   sudo -u gitea-runner gitea-runner register --config /etc/gitea-runner/config.yaml
-   ```
-
-4. Install and enable the unit:
-
-   ```bash
-   sudo cp gitea-runner.service /etc/systemd/system/gitea-runner.service
-   sudo systemctl daemon-reload
-   sudo systemctl enable --now gitea-runner
-   ```
-
-Adjust the binary path, config path, working directory and user to match your
-installation. If jobs use the host's Docker daemon, uncomment the
-`docker.service` dependencies in the unit.
