Feature request: Allow explicit ordering of skills in /skills list

Problem

The /skills command currently lists skills ordered by description token count (descending).
This makes it impossible to control the display order without artificially adjusting description lengths.

Expected behavior

Provide a way to explicitly set the display order of skills, for example via a frontmatter field:

order: 10

Or via a naming convention that is respected (e.g., alphabetical/numerical by folder name).

Current behavior

Skills are sorted by description token count (longest first), which has no relation to the logical grouping or priority the user wants to express.

Use case

Users who organize skills with a NNN-name numbering convention (000, 101, 201...) expect them to appear in numerical order in the list.
