fix: accept natively typed boolean workflow inputs (#1087)

Gitea 1.27 resolves `workflow_call` inputs server-side and sends natively typed JSON values in `github.event.inputs`, so a `type: boolean` input now arrives as a real JSON boolean. The runner coerced booleans by comparing the `any` value against the string `"true"`, which a native bool never matches, so every boolean input evaluated to `false` — including when the callee relied on its default, since the server pre-fills defaults into the event payload and the string fallback is never reached. This accepts a native bool and keeps the string comparison as a fallback, since `workflow_dispatch` inputs are still strings and YAML defaults decode to strings; servers before 1.27 never put a native bool in the payload, so they take the exact same code path as before.

The same coercion is applied to `setupWorkflowInputs` (locally-called reusable workflows, `uses: ./.gitea/workflows/x.yml`), where a `type: boolean` input was previously a native bool when passed as `with: { flag: true }` but a string when interpolated or taken from `default:`. It is now always a bool, matching GitHub, whose `inputs` context "preserves Boolean values as Booleans instead of converting them to strings". **This is potentially breaking**: `inputs.flag == 'true'` now evaluates to `false` and must become `inputs.flag == true`. That pattern is already false on GitHub (a bool compared to a string coerces to `1 == NaN`), but it works on Gitea today, so I am happy to split this hunk into its own PR if you would rather keep this one backport-safe.

Fixes #1082

+If you omit `-c`, built-in defaults apply (same as an empty YAML document).
 
-| Variable | Effect |
+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.
-| --- | --- |
-| `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) |
-
-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.
 
+> **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.

It is a pointer to distinguish between false and not set; if not set, it defaults to true.
+	SetActEnv             *bool             `yaml:"set_act_env"`              // SetActEnv controls whether the ACT=true environment variable is injected into jobs. It is a pointer to distinguish between false and not set; if not set, it defaults to true. Set it to false so workflows gated on `if: ${{ !env.ACT }}` behave like on GitHub.

Enable only for jobs that need an interactive terminal; tools like docker build emit redrawing progress frames into the captured log when a TTY is present. Applies to both host and docker backends.
 	PostTaskScript        string            `yaml:"post_task_script"`         // PostTaskScript is the path to an executable script run on the host after each task's cleanup completes. Empty disables the hook. On Windows use .exe/.bat/.cmd; PowerShell (.ps1) is not supported yet as the configured path.
 	PostTaskScriptTimeout time.Duration     `yaml:"post_task_script_timeout"` // PostTaskScriptTimeout caps how long the post-task script may run. Default is 5m when post_task_script is set.
