feedback1 WB: bounty-half evidence stated as a trend with its counter-evidence; queued free offers counted on the pill and header

- tools/build-data.mjs bountyDraftHalf: exact faction-series counts (12 of 18 two-battle cards bring first-half
  enemies, 5 outside the wave tables, enemyeffect_12_4 a second-half attachment), base-HP gradient, the user's
  two-battle recall; counter-evidence (假想敌 named enemyInitial_*, the unread NGA R3 guide); the split marked
  [ASSUMED] with its flip; data unchanged
- server/match/choices.js, docs/META.md, docs/DATA.md: the split marked [ASSUMED]
- m.private shop.rewardOffer.queued: offers waiting behind the shown one; the header says 之后还有 N 项 and the
  reminder pill +N (a 定向投放 behind a promotion reward put off)
- tests: corrected headers, the stale bountyTiers fixture dropped, queued checks (unit + opt-in e2e on desktop
  and 756x366)

  *     “复仇者” 6, “庞贝” 2, W 1, 萨卡兹百夫长 2, “邪魔的利刃” 3, 碎骨 1 — with the team at LP 6 / 10 / 9 / 15: a late

+ *   - the user's playtest #6 report "悬赏决策的敌人…正常只会在选择之后出现两回合" (DESIGN §20.6): the bounty met most
+ *     often — the R3 draft every 绝境 / 终极 match has — lasts two battles.
+ * Counter-evidence, not reconciled: the multi-round 假想敌 cards are enemyInitial_1..6, a name like the enemy_initial_*
+ * events (used here as the first-half header); a community guide "第三回合懸賞怪机制,数值及对策" (NGA tid 46551276,
+ * linked from Bahamut 12316; NGA needs a login, unread) may describe the R3 pool. The pre-series cards follow the

+ * (enemyeffect_3_2_e / 3_4 / 4) go to the late drafts, while 山海众头目 is offered early through enemyeffect_14_6.
+ * Rule [ASSUMED beyond the evidence above]: a "接下来两场作战" card (data `round` 2) is a first-half card; a "下场作战"
+ * card (the boss bounties, the 特异 giants, the faction _7 / _8 cards, the e3_* cards, 源石虫·特训) and a multi-round card
