test(cli): prevent DATABASE_URL disclosure in help

[hardbyte]

Summary

• add a process-level regression test proving awa --help never renders a resolved DATABASE_URL
• cover both the full credential-bearing URL and password sentinel

Current main already reads DATABASE_URL outside Clap after the named-context work, so no runtime change is required there.

Validation

• cargo test -p awa-cli --test help_cli_test
• cargo fmt --all -- --check
• SQLX_OFFLINE=true cargo clippy --all-targets --all-features -- -D warnings
• SQLX_OFFLINE=true cargo build --workspace

Summary by CodeRabbit

• Tests
  • Added coverage to verify that help output references the DATABASE_URL setting without exposing its secret value.

📝 Walkthrough

Walkthrough

The pull request adds an integration test for awa --help. The test sets a secret DATABASE_URL, verifies successful execution, checks that DATABASE_URL appears in the output, and confirms that the secret value does not appear.

Changes

Help output security

Layer / File(s)	Summary
Help output disclosure test awa-cli/tests/help_cli_test.rs	The test runs awa --help with a secret DATABASE_URL. It checks command success, confirms DATABASE_URL appears, and rejects the secret URL and password from combined stdout and stderr.

Estimated code review effort: 1 (Trivial) | ~3 minutes

Merge Risk: ⚪ Minimal · up to 70cfa

This test-only change strengthens protection against DATABASE_URL disclosure without changing runtime behavior. The PR is merge-ready after normal review; a minor follow-up could make the test assert the exact resolved source marker and redacted URL, but no actionable merge-blocking risk remains.

Poem

A rabbit checked the help command bright

DATABASE_URL stayed in sight
The secret URL hid from view
Its password vanished too
Safe output won the night

- Around line 19-21: The help CLI test should verify the fully resolved,
redacted target rather than only checking that DATABASE_URL appears. Update the
assertion in the rendered help test to match the exact source marker and
redacted URL produced by ResolvedTarget::describe, while retaining the checks
that the secret URL and password are absent.
