fix: man0u1 F'lhaminn dual-spawn misdirection — scope the gate muster…

[swstegall]

… apart from the Concern stage

Class-scoped SetENpc(FLHAMINN=1000038) armed BOTH public F'lhaminn spawns at SEQ_060 and SEQ_075: the Gate of Nald muster (spawn 2435, zone 170) and the Concern stage (spawn 2433, zone 209). At SEQ_060 the marker pulled the player into the Miner's Guild for the gate wait-texts (no cutscene — live run 2026-07-10 02:52), misdirecting them so the SEQ_075 escort-payment cutscene (processEvent200 + 3,000 gil) was never sought and the quest soft-locked in front of the Alchemists' Guild (Nogeloix only claims at SEQ_080).

Retail scopes them apart: marker 11001014 at 060 is a gate-side positional glyph and the stage is empty until 075 ("she oft takes the stage around this time of day", text 390).

• seed/099: mint gate-variant class 1099100 (PopulaceStandard, displayNameId 1900054, appearance cloned from 1000038) and repoint spawn 2435; idempotent, verified by double-apply.
• man0u1.lua: SEQ_060 arm + wait-talk branch re-keyed to FLHAMINN_GATE; SEQ_075 stays on base 1000038 which now resolves uniquely to the stage.
• quest_apply.rs: debug breadcrumb in apply_quest_start_sequence — the hook-path drains logged nothing, making SEQ 45/58/70 hops invisible and the run look out-of-sequence when it wasn't.
• content-test: expectNoEnpc/expectGil/expectNpcLsMsg matchers; SEQ_060 and SEQ_075 scoping + payment assertions (18/18; mutation-checked).
• design doc: checkpoints 7 (fix + live-verify steps) and 8 (accepted divergence: stage copy present before 075).

Existing saves self-heal: the ENPC set is rebuilt by onStateChange at login and migrations apply at boot — the live save parked at sequence=75 continues without surgery.
