feat(skills): add curated skill repo links to Skills settings page

Add a "Browse skills online" section to the Skills settings panel with
clickable links to places users can find and download SKILL.md skills
(Anthropic Skills, the agentskills.io open standard, the Claude Code
Marketplace, and SkillsMP). Each link opens in the browser and is paired
with a short description; a hint directs users to drop a downloaded skill
folder into a scanned directory and hit Reload.

This is a lightweight first step toward skill discovery, ahead of a full
marketplace-style installer.
