Summary

A review comment on #7356 raised a follow-up product question about the default output for azd auth token.

Original review comment: #7356 (comment)

Context

The suggestion was to consider making azd auth token default to JSON output so that running the command with no --output flag behaves the same as --output json.

Why this matters

For users, the default output format affects how easy the command is to use in shells, scripts, and tooling:

• raw token output is convenient for command substitution and piping
• JSON output is convenient when callers need both the token and expiry metadata

Follow-up questions

• Should the default experience prioritize shell-friendly token output or machine-readable JSON?
• If the command keeps raw token output by default, do we want another affordance for richer output beyond --output json?
• Do any docs or examples need to be updated once the default behavior is finalized?
