#779 SKILL.md Common Commands: model type search uses wrong command and syntax

The Common Commands section of .claude/skills/swamp/SKILL.md (line 55) shows:

swamp model search @<type>   # find available model types

This is wrong on two counts:

1. swamp model search searches model definitions, not model types.
2. The @<type> format is not a valid query argument for swamp model search.

To find available model types, the correct command is:

swamp model type search [query]

The fix would replace line 55 with the correct swamp model type search form, matching the Quick Reference table in references/model/guide.md.
