* fix: clarify that local skills work automatically, workspace skills are for team sharing
Users were confused, thinking they needed to re-upload locally installed skills
(e.g. .claude/skills/) to Multica before agents could use them. Updated UI text
across the skills page, agent skills tab, onboarding, and docs to clearly
distinguish between local skills (auto-discovered) and workspace skills (for
team-wide sharing).
Closes#972
* feat(views): replace inline text with info banner for local skills hint
The "local runtime skills are always available" message was buried in
the description text and easy to miss. Move it into a visible info
callout banner with an icon so users notice it immediately.
