v1.0.7: packaging (author profile + docs)

v1.0.7 is a packaging/docs release; no functional change from v1.0.6.

• manifest author.url now points at the publisher GitHub profile (https://github.com/customd).
• Submission/docs tidy-up.

Carries forward v1.0.6: in-chat partner_central_select_account (account/role pick + switch), the read-only verify_connection reachability probe against your default catalog, and the v1.0.5 "Could not attach" startup fix.

To upgrade: reinstall the attached aws-partner-central.mcpb in Claude Desktop, Settings -> Extensions.
