CC2 review fix round: latch scope narrowed, AD-100, creationFailed reason key

Browse source 
F1 (MEDIUM): the correlation-latch docs claimed replies are never
misattributed; in truth an overlapping send OVERWRITES the latch and the
first reply routes to the newest request's event. Narrowed all three doc
sites to the exact contract (single outstanding request; overlap refusal
is CC3's Runtime verification gate, retail's DoFinish UNDEF-state rule)
and pinned the overwrite behavior with
OverlappingSend_OverwritesTheLatch_ReplyRoutesToNewestRequest.

F2 (LOW): filed register AD-100 for the drop-unless-armed deviation —
retail's Handle_CharGenVerificationResponse@0x0055E8B0 has no armed gate
and processes whatever arrives against its persistent verification state.

F3 (LOW): doc note in CharacterCreate.cs — ACE double-sends NameInUse
(IsCharacterNameAvailable runs twice; the first callback's return exits
only the lambda), so the second reply hitting the drop path during a
connected gate is EXPECTED, not a defect.

F4 (LOW): creationFailed's enum-member key renamed name -> reason and the
ATTEMPTED character name added as name, before any consumer shipped —
one status vocabulary must not give the same key two meanings
(characterCreated.name is a character name). Contract, writer, tailer,
and shape-pinning tests updated in lockstep.

F5 (LOW): the thread-id probe-note pointer now cites
ProbeNetLogOutbound's doc comment, where the note actually lives.

Fidelity fold (reviewer's positive note): the latch is retail's OWN
discriminator one layer down — 0x0055E8B0 case 1 branches on
GetVerificationState()==PENDING (create) vs not (restore) — now cited in
both the latch doc and CharGenVerificationResponse.cs.

Core.Net 994, Runtime 1667, Launcher.Core 324, all green Release.
