Initial commit: Velum Raycast extension

Pseudonymize-and-AI workflow for handling PII-sensitive text via the
Velum API and Raycast AI. Commands cover end-to-end email summary and
reply, briefing/action-items/structured-data extraction, manual
pseudonymize/depseudonymize on selection or clipboard, and session
management. Includes Raycast 2.0 Beta workarounds for selection capture
and rich-text clipboard.
