fix(streaming): preserve exact live projection identity

Browse source 
Carry RuntimeEntityKey through spatial residency, visibility transitions, rebucketing, quiescence, landblock retirement, and origin recentering. This prevents stale incarnation edges from mutating a replacement projection while retaining the static DAT-entity path.

Validated by 104 focused ownership/streaming tests, the Release solution build, and 8,444 complete Release tests with five existing skips.
