Feature request: alphabetical or configurable sorting for the slash-command autocomplete dropdown

Is your feature request related to a problem?

When typing / (e.g. /ido) in the Claude Code desktop app, the autocomplete dropdown lists matching custom skills/commands in what appears to be an arbitrary order — not alphabetical. With many similarly-prefixed custom skills (e.g. ido-analyze-emails, ido-agents-system-manager, ido-code-save-and-publish, ...), scanning an unordered list to find the right command is slow and error-prone.

Describe the solution you'd like

Sort the slash-command autocomplete entries alphabetically by default (within equal fuzzy-match relevance), or expose a setting (e.g. in settings.json) to control the ordering — alphabetical / relevance / recency.

Describe alternatives you've considered

• Renaming skills to force an order — doesn't help, since the current order isn't alphabetical.
• No documented setting, env var, or config option currently controls this ordering (checked interactive-mode and commands docs).

Additional context

• Claude Code 2.1.72, desktop app, Windows 11 Pro
• Related (closed, different scope): #19107 — autocomplete selection/highlight inconsistency; suggests the ordering may come from internal/stale state rather than intentional design.
