🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Qualify the jmcomic[plugins] option for calibre_metadata.

The failed-fast message presents pip install jmcomic[plugins] as a complete alternative, but pyproject.toml excludes jmcomic-calibre from the [plugins] extra. The plugin requires the Git-based dependency specification, so option 2 alone does not make calibre_metadata usable.

Update the generic guidance to state this exception and retain the plugin-specific Git installation command. Do not change the extra unless the project intends the bundle to install this Git dependency.

In `@src/jmcomic/jm_plugin.py` at line 2152, Update the failed-fast guidance
around calibre_metadata to clarify that pip install jmcomic[plugins] does not
install jmcomic-calibre and is therefore insufficient by itself; retain the
existing plugin-specific Git installation command for jmcomic-calibre, without
changing the extras configuration.
