test: remove all test files for a clean restart (task 0003)

Temporary: clear the entire test suite (unit, subprocess, the shared
helper, and the parser-integration placeholder) so the tests can be
rebuilt from scratch. Fixtures and the test tooling (bunfig, report
script) are kept. Note: `bun test` now errors on an empty suite, so the
flake's tests check is red until tests return.
