feat: config command to edit config files (#1140)

Browse Source 
Changing a setting after `generate-config` meant hand-editing YAML, which is awkward in provisioning scripts. `config` now edits an existing file in place:

```bash
./gitea-runner -c config.yaml config set runner.capacity 4
./gitea-runner -c config.yaml config set runner.envs.MY_VAR value
./gitea-runner -c config.yaml config add runner.labels 'ubuntu:docker://node:22'
./gitea-runner -c config.yaml config remove runner.labels 'ubuntu:docker://node:22'
./gitea-runner -c config.yaml config get runner.labels
```

Edits go through the YAML node tree, so comments, key order and the blank lines between top-level sections survive — a test asserts that appending a label to `config.example.yaml` changes nothing but the added line. Keys are resolved by reflecting over the `Config` struct's yaml tags, so an unknown key or a value of the wrong type is rejected before the file is touched. The write is atomic and keeps the file's symlink, owner, mode and line endings.
