Omnio: refresh slash-command registry when a skill is created/edited/deleted

[ppazosp]

A skill created mid-session — e.g. via /learn, which authors through skill_manage — wasn't invocable until the gateway restarted. skill_manage cleared the skills system-prompt cache on success but never rescanned the slash-command registry (agent.skill_commands._skill_commands), which only refreshes on /reload-skills or a platform change. The result: GET /v1/skills returned the new skill with command: null, and the chat path wouldn't expand /<command> — so a just-learned skill couldn't be run from the UI palette or by typing it.

Fix

Rescan the registry (scan_skill_commands()) in skill_manage's success block for the actions that change the skill set or a skill's name — create / edit / patch / delete. write_file/remove_file touch only supporting files (not names), so they skip the (relatively costly) rescan. A rescan failure is logged, not silently swallowed.

This sits right next to the existing clear_skills_system_prompt_cache() call — same "invalidate caches on a successful skill mutation" seam, just covering the registry that was missed.

Tests

tests/tools/test_skill_manager_tool.py — TestRegistryRefreshOnMutation:

• create → /test-skill resolves in get_skill_commands()
• delete → the command is gone
• write_file → no rescan (supporting files don't change the registry)

Full skill_manager suite green (97 passing), ruff clean.

Context

Pairs with an Omnia-side change (palette refetches /v1/skills on open) so a newly-created skill also shows up in the chat's / menu without a reload. Follow-up to the slash-command palette work (hermes #17 / omnia NousResearch#3315).
