Captures the full teleport-flow journey (Slice 1 kept, Slice 2 hold built +
reverted), the root-cause findings (the IsLandblockLoaded key bug + the real
foundation problem: destination doesn't stream fast/complete during teleport,
likely _datLock starvation from the CreateObject flood), the open foundation
issues (#138 slow/incomplete streaming, lost-collision-after-teleport, FPS
leak Work-C, the PortalSpace freeze-vs-run-through question), and the clean
baseline (dd2eb8b). Written as evidence + open questions, not conclusions, so
a fresh session can re-examine the whole approach.
