Phase 0 hygiene: remove GE_OBJT probes (D321 closed; M-192 item 7)

The D321 stage-flag writer probe (chrSetStageFlags/chrUnsetStageFlags in
chraction.c, GAS_RELEASING destruction timestamp in propobj.c) did its job
(D321 trigger chain mapped + closed); all three blocks were #ifdef PORT
diagnostics with no N64-build or runtime effect when unset. Dropped the
GE-ENV-PROBES.md row too (drift check passes).

getenv hot-path sweep (D302 follow-up, HANDOFF M-192): function-level scan
of all 171 GE_* getenv sites found no uncached calls at frame/triangle rate
-- the only candidates are snd.c's event-rate probe guards (all #ifdef PORT)
and bossReturnTitleStage (once per title return). fast3d has zero raw
'if (getenv(' sites.
