[Bug] Slash-command dropdown collapses namespaced plugin skills to single entry

Bug Description
Title: Slash-command dropdown collapses a plugin's skills to a single visible entry When a plugin registers multiple skills, the live / autocomplete dropdown shows only ONE entry for that plugin instead of listing all of them. Repro: - Install a plugin exposing several namespaced skills, e.g. project-wiki with project-wiki:sync, project-wiki:lint, project-wiki:ingest, project-wiki:adapt, project-wiki:query, project-wiki:migrate (all registered, identical frontmatter). - At the start of a prompt, open the / menu and type a partial of the plugin prefix (e.g. "proj"). Expected: - The dropdown lists ALL matching plugin entries (all six project-wiki:* commands). Actual: - The dropdown shows only ONE entry, displayed by its bare skill name (e.g. "sync"), with no way to see the sibling skills in the same list. Pressing Tab inserts the full token (project-wiki:sync), and Tab/fuzzy completion does resolve correctly — but the live suggestion list never surfaces the other five. Notes: - The dropdown appears to match/display the bare skill name rather than the full namespaced token, and collapses multiple skills of the same plugin into a single visible row. - Typing the full prefix with trailing colon (/project-wiki:) does not reliably list all entries either. Request: - When the typed text matches a plugin prefix, list ALL plugin:* skills in the dropdown, not just one. Environment: Claude Code CLI on Linux.
