[BUG] Refusal to improve test suite

[adlai]

Describe the bug

The test framework changes package signatures, causing certain workflows to produce unusable images; the result of this is that the test framework should only be run from a fresh image, thus this is not a critical problem and possibly even a good feature!

To Reproduce

Steps to reproduce the behavior:

1. Use portacle or something, (ql:quickload "chanl")
2. Run the tests with ,test-system chanl
3. Write and commit a new test case; if the new test is in a separate file, add that to the chanl.tests ASDF definition.
4. Repeat ,test-system chanl

Expected behavior

Package signatures should not prevent the test framework from running, as the violation was limited to (export 'run-all-tests).

Screenshots or Error Logs

Make your own.

Minimally, the failure triggered by the package lock should include a style-warning recommending to reload and run the test suite in a separate image; possibly with a restart that handles part of this chore.
