Subject: [PATCH 1/2] [Devourer] Model Voidfall building procs as a
 pseudo-random distribution

The builder proc is a PRD in game, not a flat roll: the per-cast chance starts near 16% after a proc and rises with each miss, averaging the nominal 35% and guaranteed by the 7th cast. Verified against ~24k builder casts from logs.

Use accumulated_rng with prd::find_constant, and check the spending buff before the roll so the accumulator only advances on real builder attempts. Mean proc rate and DPS are unchanged; the cadence is less streaky.
