* feat: add global skill packages with local ZIP import and personalization layout
Introduce instance-level skill packages (DB + disk), mount them on agents, and
support SkillHub/URL/ZIP import. Merge related schema into migration v2 and
cover the zip import path with frontend and API tests.
* fix: hot-sync skill package mounts and dark-mode package cards
Avoid full agent rebuild when mounting packages so Experts UI no longer
hits AGENT_NOT_FOUND; accept workspace-scoped local backends on Windows;
use theme token for package list card background.
