fix: replace mock.module with spyOn for logger in timeline-formatting tests

mock.module() globally replaces the logger module for ALL test files
running in the same Bun process, causing logger.formatTool to be
undefined in logger-format-tool.test.ts. Using spyOn instead keeps
the real Logger instance and only stubs individual methods.

This was the root cause of the recurring CI-only test failure —
mock.module poisoned the module cache across parallel test files.
