Bump mercadopago to 63ff263c (v2 + PreToolUse hook gating) (#1949)

Bumps the mercadopago plugin pin from 1de8d97e to 63ff263c (latest main).

v2 replaces the mcp-launcher.sh keychain-read / npx -y mcp-remote
wrapper with a plain type:"http" MCP entry pointing at
https://mcp.mercadopago.com/mcp, and consolidates 13 skills into 4
orchestration skills. The pinned SHA also includes the May 19 fix
that gates the PreToolUse hook on project relevance so it no longer
runs on unrelated projects.

Description updated to match the partner's v2 self-description.
