Suppress auth-ado log output by default, add ARTIFACTS_HELPER_VERBOSE

[Copilot]

The ADO auth extension was emitting step messages to stdout during normal package operations, cluttering build output with authentication details users don't need to see.

Changes

• Silent by default: Authentication now runs without output unless ARTIFACTS_HELPER_VERBOSE=true is set
• Warnings preserved: Timeout and error conditions still emit warnings regardless of verbose setting
• Version bump: 3.0.1 → 3.0.2

Implementation

Added conditional logging functions in auth-ado.sh:

log_step() {
    if [ "${ARTIFACTS_HELPER_VERBOSE}" = "true" ]; then
        echo "::step::$1"
    fi
}

All informational messages (::step:: prefixed) now use log_step() or log_message(). Error/warning messages bypass the check.

Usage

Enable verbose output for troubleshooting:

export ARTIFACTS_HELPER_VERBOSE=true

Documented in NOTES.md with examples.

<issue_description>Hello!

We recently started seeing this output from the ado auth extension in our codespaces :

> yarn build-scope acui-avatar
::step::Waiting for AzDO Authentication Helper...
::step::Running ado-auth-helper get-access-token...
::step::✓ Access token retrieved successfully

...

Is there a way to mute this output?

Thank you!

@markphip https://github.com/microsoft/codespace-features/blob/main/src/artifacts-helper/scripts/auth-ado.sh @markphip It can do whatever makes sense including removing the messages. Does Codespaces offer any kind of existing environment variable it could look at to decide when to send them and when not? They are useful when the command you are running is waiting for the auth helper to be installed so that you understand why the command is not doing anything.

Are the messages causing a problem?</comment_new>
<comment_new>@markphip
Submit a PR that removes them or conditions them. I was more wondering if when Codespaces runs in Debug mode if there is something set that could be the only time they show. Or ir could just be a newly introduced one that someone could set when troubleshooting to see what is happening. Agree it could be silent by default

You can also use artifacts-helper:2</comment_new>
