revert(teleport): drop the Slice 2 outdoor readiness-gate hold

Browse source 
User-tested: the Slice 2 'hold outdoor until landblock loaded' gate made
EVERY outdoor teleport a ~10 s freeze, because the destination landblock
does NOT load fast during the hold (lbs=0 the whole time — the #138
streaming gap + _datLock starvation from the CreateObject flood). The hold
was band-aiding a broken/slow foundation rather than fixing it, and it never
actually prevented the #145 edge cascade anyway (it force-snapped onto
NO-LANDBLOCK after the timeout regardless).

Reverts ad8c24e..c880973 to the pre-Slice-2 state (00ef47e): outdoor places
immediately again (fast teleports). The genuine bug found along the way —
IsLandblockLoaded queried the wrong key form (& 0xFFFF0000 vs the stored
| 0xFFFF) — is preserved in the history (c880973) and will be re-applied when
we re-introduce a proper hold ON A FIXED FOUNDATION.

Decision (user, 2026-06-21): fix the foundation FIRST — fast/complete
streaming during teleport (#138), the post-teleport lost-collision bug, and
the FPS leak (Work item C) — then revisit the teleport-flow animation. Slice 1
(the pure TeleportAnimSequencer) stays in (dormant, unwired, harmless).

// Regression for the Slice 2 key-mismatch bug (#145 apparatus re-test, 2026-06-21):
// landblocks are stored under the EncodeLandblockId form (low 16 = 0xFFFF), but the
// teleport gate (TeleportArrivalReadiness) queries with (destCell & 0xFFFF0000) (low
// 16 = 0x0000). A raw ContainsKey never matched, so the outdoor gate was permanently
// NotReady and every outdoor teleport timed out at 10 s. IsLandblockLoaded must
// normalize so ANY id within the landblock resolves to the stored entry.
