Prepare Connect v0.1 package metadata

[HDauven]

Summary

• bump @dusk/connect package metadata from 0.0.1 to 0.1.0
• use @dusk/connect consistently for npm and JSR package metadata
• add JSR publishing metadata for @dusk/connect@0.1.0
• add JSR import/publishing docs, module docs for public entrypoints, and TSDoc for exported API symbols
• update the v0.1 release checklist so the package-version item is now a metadata confirmation instead of a pending bump
