silverwind 1d6c6ffef9 enhance: improve config, comment out values in example file (#1145)
`config.example.yaml` now has every value commented out, as gitea's `app.example.ini` does, so it documents each option with its default instead of imposing it. Copying it no longer pins values the runner would otherwise pick, and a changed default reaches configs that never named the option.

`config init` writes the file to configure: a header comment and no option, so every option keeps its default. It refuses to overwrite an existing config without `--force`, and writes `config.yaml` in the working directory when `-c` is absent.

`config set`, `add` and `remove` keep such a file readable. Comments go back to the indentation they were written at, which the encoder drops for a comment block that has no key below it, and a file of only comments keeps its text instead of being emptied by the first edit.

Also rewrote the config docs sections for clarity.
