fix(post-update): clear Claude plugin cache on update

Browse Source 
The Claude plugin cache at ~/.claude/plugins/cache/leo-claude-mktplace/
holds versioned copies of .mcp.json files. When we update .mcp.json
to use run.sh instead of direct python paths, the cache retains old
versions, causing MCP servers to fail.

Now post-update.sh clears this cache, forcing Claude to read fresh
configs from the installed marketplace on next session start.
