chore: inject the version into main instead of a module path

The `-X` target carried the full module path in both the Makefile and
.goreleaser.yaml, so any change to the module path silently turned the
injection into a no-op and shipped a binary reporting "dev". Target
`main.version` instead, which no longer names the module, and fail
`make checks` when the injection stops taking effect.

 `config get`, `set`, `add` and `remove` use `config.yaml` (or `config.yml`) from the working directory, then from the directory of the binary, and print their choice to stderr. `config init` writes `config.yaml` in the working directory, and refuses to overwrite an existing config without `--force`. Pass `-c` for another path.
 
-#### Tool cache
-
-Setup actions like `setup-go` install tools into `RUNNER_TOOL_CACHE`, which is `/opt/hostedtoolcache` inside a job. `runner.tool_cache_mode` selects what backs it:
-
-| Mode | Tool cache | Trade-off |
-| --- | --- | --- |
-| `none` (default) | Per job, provided by the job image | A version the image lacks is downloaded in every job |
-| `shared` | One volume reused by every job | Two jobs writing the same tool version at once corrupt it, so use it only with `runner.capacity: 1` |
-
-With `none`, tools must come from the job image. Install them into `/opt/hostedtoolcache/<tool>/<version>/<arch>`, with an empty `<arch>.complete` file next to the directory:
-
-```dockerfile
-RUN GO=$(curl -fsSL 'https://go.dev/dl/?mode=json' | grep -oP '"version": "\Kgo1\.26\.[0-9]*' | head -1); \
-  DIR="/opt/hostedtoolcache/go/${GO#go}/x64" && \
-  mkdir -p "$(dirname "$DIR")" && \
-  curl -fsSL "https://dl.google.com/go/${GO}.linux-amd64.tar.gz" | tar -xz -C /tmp && \
-  mv /tmp/go "$DIR" && \
-  touch "${DIR}.complete"
-```
-
-A workflow requesting a minor version, `go-version: "1.26"`, resolves to the newest matching version in the cache, so a patch update in the image still hits it.
-
-Of the [runner images](https://gitea.com/gitea/runner-images), the `-full` flavour is the one that ships tools in this layout.
-
-`gitea-runner exec` reads no config file and takes `--tool-cache-mode` instead, defaulting to `none`.

 Each runner starts its own cache server automatically. Cache entries are local to that runner — runners do not share a cache by default.
 
-**Eviction**
-
-An entry nothing has read or written for `retention` is removed, and a repository past `repo_size_limit` loses its least recently accessed entries until it fits; `size_limit` caps the whole cache the same way. Age alone never retires an entry still in use, and whatever these allow, the cache keeps free space above `health_check.min_free_disk_space_mb` when health checks are enabled.

A bundle it does not recognise is left alone and keeps to v1. The same edit lets the stock `actions/upload-artifact` and `actions/download-artifact` work from `v4.4.0` on, without the `gitea-upload-artifact` fork, so it is made whatever `v2` says: that setting only governs the API the runner advertises. Set `runner.patch_actions: false` to leave every bundle exactly as shipped, an escape hatch for an action the edit breaks. The artifact actions then refuse again and the cache client keeps to v1.

 Alternatively, mount the same NFS/CIFS share on every runner and point `cache.dir` at it — simpler, but with weaker isolation between repositories.
 
 **S3 / MinIO** — mount object storage as a FUSE filesystem (e.g. [s3fs](https://github.com/s3fs-fuse/s3fs-fuse) or [goofys](https://github.com/kahing/goofys)) and set `cache.dir` to the mount point.

-#### Local job logs (`log.job.dir`)
-
-Set `log.job.dir` to a path and the runner writes a copy of every task's log there as `<start time>-task-<id>.log`: the rows exactly as Gitea received them, with the same secrets masked and the job's result on the last line. Off by default, and what Gitea shows does not change.
-
-#### Secret masking
-
-A job's secrets and its `::add-mask::` values are hidden from what the runner writes and uploads: the job log, the local copy above, job summaries, and the names of the containers it creates. A job output carrying one is skipped with a warning rather than sent masked, as GitHub does, so a downstream `needs.<job>.outputs.<name>` reading it is empty.
-
-`log.job.retention` (default `168h`) is how long a log is kept, expired ones being deleted as new tasks start, and `log.job.max_size` (default `1GB`) caps one log. Keep `retention` above `runner.timeout` so a long job cannot outlive its own log, and prefer local disk, the file is written while the job runs. Only the runner's own user can read it.
