Description

Describe the feature you want

Add an option to turn enable/disable park head after power loss recovery (like advanced pause).
This could be done after homing XY axes, if enabled, then the head moves to the park point and waits for nozzle and bed to reach the printing temperature.

Example:
#define POWER_LOSS_PARK_HEAD // Park the nozzle on resume.

Additional context

For printers like Ender 5 Plus, that have the endstops on the rear side, this could be useful for maintenance/cleaning before resuming or for removing the purged filament.

Research direction

Start by locating the existing power-loss recovery and advanced-pause implementations, then trace the post-homing resume flow. Done means a configurable park-head option supports the described move and temperature wait before resuming, including the disabled behavior.
