- Refactored logger.time() API to accept function references and arguments separately instead of wrapped callbacks. - Replaced RingBuffer-based timing with wall-clock markers and async span tracking for improved timing accuracy. - Updated 20+ call sites across executor, kernel, main, and tools modules to use new logger.time() signature. - Removed parsePath() helper function and inlined path.split() calls in settings module. - Added test case verifying model selection without auth validation during startup.
