gitea can not consume the runner's api by version while it's version mismatches the module version:
```
go: gitea.com/gitea/runner@v3.0.1: invalid version: module contains a go.mod file,
so module path must match major version ("gitea.com/gitea/runner/v3")
```
Fix that by bumping the module version now. The existing `v3.0.0` and `v3.0.1` tags stay unusable, so a new tag is needed after this lands.
Also drop the version `-X` linker flags, which would otherwise have to repeat the new path in both `Makefile` and `.goreleaser.yaml`, where a stale path makes injection silently no-op. Go has recorded the module version in the build info since 1.24, so `Version()` reads it from there, keeping the variable as an override for builds without a VCS stamp.
That part started as https://gitea.com/gitea/runner/pulls/1137 but belongs here: the stamp resolves against the tags that are legal for the module path, so without the `/v3` bump it would report `v1.0.9-0.<ts>-<sha>`. Since `release-nightly.yml` triggers on every push to `main`, splitting them would publish a nightly with a `v1` version.

## Summary
Mirrors the GitHub Actions runner behaviour where each `run:` step shows a collapsible **"Run \<command\>"** section containing the script, shell command, and environment variables before the actual step output.
### What changes
- **`pkg/runner/step_run.go`**: In `stepRun.main()`, two new executors are added to the pipeline:
1. `logRunGroupHeader()` — runs after `setupShellCommandExecutor()` (so `sr.cmdline` is already resolved). Emits a `::group::Run <step>` log entry followed by the interpolated script, the full shell command line, and the step's env vars (sorted, internal vars filtered out).
2. The existing execution function now has `defer rawLogger.Infof("::endgroup::")` so the group is closed after the step finishes, regardless of success or failure.
### Env var filtering
Internal runner vars are hidden (`GITHUB_*`, `GITEA_*`, `RUNNER_*`, `INPUT_*`, `PATH`, `HOME`) — only user-relevant vars are shown, matching what GitHub Actions displays.
### Example output
```
▼ Run cargo build
cargo build
shell: bash --noprofile --norc -e -o pipefail {0}
env:
CARGO_HOME: /home/runner/.cargo
CARGO_INCREMENTAL: 0
CARGO_TERM_COLOR: always
<actual build output>
```
