fix: move mcp_servers to metadata.json to prevent silent plugin.json rejection

Browse Source 
Claude Code's strict schema validation silently rejects plugins with unknown
root-level fields in plugin.json (anthropics/claude-code#20409).
Moved mcp_servers to separate metadata.json files.
Updated install/uninstall/list scripts to read from new location.
Added cache clearing to switch-profile.sh.
