test: assert observable CLI behavior

[ScriptedAlchemy]

Replace tests that pin implementation constants with an assertion on the CLI's observable error fallback. Keep executable coverage in the packed installation smoke test, including both gbot and its grok-bot alias, plus gbot-install.

Validation: full local check passed (201 unit tests and 13 route tests), actionlint passed, and a real packed installation ran all three executable help commands. The final contribution added only whitespace cleanup; the affected suites passed again (11 tests). Hosted checks remain queued without starting.

Keep coverage for the grok-bot executable alias

Deleting this test leaves the published grok-bot command unverified: the packed-package smoke test in .github/workflows/ci.yml invokes only gbot and gbot-install, while package.json still exposes the long-standing grok-bot alias. If that alias is removed or misspelled, CI will remain green but existing users invoking grok-bot will lose their executable; retain a focused alias assertion or execute it in the packed-package smoke test.
