T08 iter 6: game end and the three scoring modes; AM-1 at 100%

- GR-R09: after Round 5's End the game ends and scoring runs instead of
  the round advancing.
- GR-E01: claimed Problems sum their printed values against the
  player-count threshold (2p 5, 3-4p 7, 5-6p 9 in dataset 0.1).
- GR-E02 SHARED GROUND: shared score, Mastery reduced per Blame token
  and per Denied Problem.
- GR-E03 COMMON PROBLEM: personal score is claimed value less Blame,
  tiebroken by lower Stress then more Bonds.
- GR-E04 BONDED COALITIONS: connected components over Bonds only, so
  Rivalries do not connect and an unbonded player is a coalition of
  one; tiebroken by lower combined Stress then fewer Blame.

Ties yield every tied candidate rather than an arbitrary pick, which is
what "shared victory" in GR-E03/E04 asks for.

AM-1 rule coverage is now 58/58 (100%), 21 scenarios, 17 tests.

Caveat recorded rather than papered over: GR-E02's "successes" is not
defined in dataset 0.1. It is implemented as the count of claimed
Problems and both scoring scenarios are marked provisional, so a
ground-game ruling flips a scenario rather than the kernel.
