Aligns the slash-menu cache with `discover_in_workspace`, so global `~/.deepseek/skills` and `~/.claude/skills` skills appear alongside project-local `.agents/skills` in the slash menu, `/skills` listing, and `/skill <name>` lookups. Also strips surrounding YAML quotes from `SKILL.md` frontmatter values, so a skill declared as `name: "hud"` registers as `hud` and matches prefix lookup. Closes #1068. Thanks to @AlphaGogoo / @Duducoco for the fix and the test.
