[edras-create]

Summary

Refresh five source-backed metadata cells for three providers used by Somnia:

• update PublicNode's provider description to its current 75-chain, privacy-first positioning and explicitly record Somnia support;
• add Pimlico's official support email and platform documentation link;
• add Sequence's official Discord invite and platform website link.

• The modified CSV files parse successfully, remain sorted by slug, and their JSON fields are valid.
• Fresh provider-specific and metadata-batch PR searches found no existing changes to these five cells.
• This PR is not a blind AI-generated submission.
