Refactor the file that is currently open or explicitly mentioned by the user.

Default (no arguments): Preview mode, analyse the file and output a structured diff showing all proposed changes. Do not modify the file.
If $ARGUMENTS contains apply: Apply mode, apply all refactoring changes and rewrite the file.

Step 1: Detect the file language

Look at the extension of the target file:

If .js, .ts, .mjs, .jsx, .tsx → the language file is front-refactor-js.md
If .css, .sass, .scss → the language file is front-refactor-css.md
If .vue → the language file is front-refactor-vue.md
If .svelte → the language file is front-refactor-svelte.md
If .astro → the language file is front-refactor-astro.md
Otherwise → inform the user that this file type is not supported. Supported types: .js, .ts, .mjs, .jsx, .tsx, .css, .sass, .scss, .vue, .svelte, .astro.

The path of this skill file is always available from context. Resolve all sub-file paths relative to it.
