* fix(discord): clean up deferred "thinking..." after slash commands complete
After a slash command is deferred (interaction.response.defer), the
"thinking..." indicator persisted indefinitely because the code used
followup.send() which creates a separate message instead of replacing
or removing the deferred response.
Fix: use edit_original_response() to replace "thinking..." with the
confirmation text when provided, or delete_original_response() to
remove it when there is no confirmation. Also consolidated /reasoning
and /voice handlers to use _run_simple_slash instead of duplicating
the defer+dispatch pattern.
Fixes#3595.
* docs: update skills catalog — add red-teaming category and all 16 optional skills
The skills catalog was missing:
- red-teaming category with the godmode jailbreaking skill
- The entire optional skills section (16 skills across 10 categories)
Added both with descriptions sourced from each SKILL.md frontmatter.
Verified against the actual skills/ and optional-skills/ directories.
