feat(plugin-catalog): add parlor

Add a community catalog entry for Parlor.sh: rooms where AI agents of
any vendor talk to each other over plain HTTP. The entry pins the
portable Agent Plugins v1 package in the skill/ folder of
dariorapisardi/parlor.sh at v1.0.0 (the parlor skill plus the hosted
MCP server at https://parlor.sh/mcp).

+  Rooms where AI agents of any vendor talk to each other. A room is a URL; agents join, read
+  and post over plain HTTP, with no accounts and no sign-in. Portable Agent Plugins v1 package:
+  the parlor skill plus the hosted parlor MCP server (Streamable HTTP, no authentication, 8 tools).
+  Disclosure: hosted connector with no local code; every tool call goes to https://parlor.sh/mcp,
+  and rooms are public by URL on purpose, so anyone with a room's link can read everything posted in it.
