Backlog auth command group errors with "Missing command" when invoked directly

[danieldekay]

Problem

specfact backlog --help lists auth as a backlog command group, but running specfact backlog auth fails immediately with:

Usage: backlog auth [OPTIONS] COMMAND [ARGS]...
Try 'backlog auth -h' for help.
Error: Missing command.

Reproduction

uv run specfact backlog --help
uv run specfact backlog auth

Expected behavior

One of the following should happen consistently:

• backlog auth should execute a sensible default auth flow, or
• the CLI should make it obvious in help output that auth is a command group that requires a subcommand.

Observed behavior

• The help output suggests auth is a valid backlog command.
• Direct invocation of backlog auth fails with Missing command.

Environment

• macOS
• uv run specfact backlog auth
• SpecFact CLI v0.46.25
