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

• Bug Fixes

  • Help output for awa serve and awa callbacks serve now identifies AWA_CALLBACK_HMAC_SECRET without revealing its configured value.
  • Existing database credential protection remains in place, preventing secret URLs and passwords from appearing in help text.

• Tests

  • Added regression coverage for credential handling across all supported help screens.

📝 Walkthrough

Walkthrough

The pull request prevents callback HMAC secret values from appearing in awa serve --help and awa callbacks serve --help. It adds shared test coverage for these commands and preserves coverage for DATABASE_URL redaction. The changelog records the fix.

Changes

Help output security

Layer / File(s)	Summary
Help output secret protection and regression coverage awa-cli/src/main.rs, awa-cli/tests/help_cli_test.rs, CHANGELOG.md	The two callback secret arguments hide environment variable values in help output. Shared test logic checks command success, visible environment variable names, and absent secret values for all three credential-bearing help surfaces. The changelog records the fix.

Estimated code review effort: 1 (Trivial) | ~5 minutes

Merge Risk: 🟡 Moderate · up to 04067

The CLI now hides resolved credential values from help output and adds process-level regression coverage, but the test does not prove that the expected resolved and redacted DATABASE_URL output is rendered; a vacuous pass could therefore miss a regression, so the merge should wait for that assertion or explicit owner acceptance.

Poem

A rabbit tuned the help text bright
A secret stayed beyond the light
The variable name remained clear
While hidden values disappeared
Three guarded commands now read right

Explanation

The title accurately describes the added DATABASE_URL help-disclosure regression test. The changes also hide AWA_CALLBACK_HMAC_SECRET values from help output, so the title does not cover the primary runtime change but remains related to a real part of the pull request.

- 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.
