fix: initialize logging before planning mode check

Move initialize_logging() call to run immediately after CLI parsing,
before any mode checks. This ensures the --verbose flag works correctly
in planning mode, which previously bypassed logging initialization.

Previously, planning mode would return early before initialize_logging()
was called, causing verbose output to be silently ignored.
