Fix pause/resume chain, shared print cleanup, add CLAUDE.md

- RESUME is defined only in print/pause_resume.cfg; heat_soak.cfg's
  duplicate replaced it (no unretract, no fan restore). It now runs
  HEAT_SOAK_RESUME -> _RESUME_PRINT -> RESUME_BASE.
- PAUSE runs PAUSE_BASE first, then retracts and parks once (X20 Y345);
  a parked flag makes resume undo only what PAUSE did.
- New _PRINT_CLEANUP shared by PRINT_END and CANCEL_PRINT: heaters incl.
  iHEATER_OFF, fan, M221 S100, bdwidth off, mesh and skew cleared.
  In PRINT_END it runs after RESTORE_GCODE_STATE so the flow reset sticks.
- Add CLAUDE.md and tools/effective_config.py.
