feedback1 WB: R11 bounty drafts as groups + tier-I fill (matches 1 and 6 share a group); solo R11 weights marked assumed

The official R11 bounty drafts are not a free draw under the old rule: matches 1
and 6 show the same 特异III giant and the same four tier-II cards and differ only
in their one tier-I card; 15_7 + 13_8 come together in 3 of the 5 drafts; 10_8,
11_8 and 12_8 never show. A uniform draw under the old rule repeats 5 of 6 cards
in some pair of 5 drafts in about 2.5 % of samples.

- tools/build-data.mjs: BOUNTY_HUNTER_TEMPLATES (the 4 seen R11 groups: giant +
  tier-II cards, fill = the 5 tier-I cards seen) and BOUNTY_HUNTER (the shape an
  unseen slot draws: one giant + 1-4 tier-II cards + tier-I fill, one card per
  faction series 10-15). choices.json bountyDrafts.hunter gains slots (15),
  templates and rule. The R9 note now names the per-match explanation (leader,
  map) beside two versions. Solo 绝境 / 终极 R11 family weights are marked as
  extrapolated from co-op.
- server/match/choices.js: the hunter draft picks one of the 15 event slots: a
  seen group, or a rule group of that shape, then tier-I fill.
- test/match/feedback1-bounty.test.js: each official R11 bounty draft fits
  exactly one seen group and the rule shape; matches 1 / 6 share 5 cards;
  generated drafts: a seen group in about 4 of 15, every seen group and every
  R11 card offered.
- docs/DATA.md, docs/META.md: the R11 structure, the solo weights and the R9
  open question.
