refine(mcp): drop github, perplexity, telnyx, exa, parallel-search from the catalog batch

- github: 44 tools / ~31K schema tokens duplicating the built-in gh CLI skill
- perplexity/telnyx: api_key friction — batch policy is browser-OAuth or no-auth only
- exa/parallel-search: redundant with Hermes's native web_search backend
