Summary by cubic

Normalize MCP profile email lists by converting nil AdditionalEmailAddresses to an empty slice so JSON always encodes as []. Adds a regression test to lock this behavior.

MCP +10 -2

• In pkg/server/api/mcp/v1/types, NewProfile now defaults AdditionalEmailAddresses to mail.Addrs{} when nil to ensure stable [] JSON output.

Tests +39 -0

• Added profile_test.go verifying the field is non-nil and marshals to [].
