feat(sports): opt-in celebration and rotation capabilities

Phase B2 of the sports unification. Both features exist in only some of
the nine scoreboards, so they ship as capabilities the plugin composes,
never as `if self.<feature>_enabled` branches inside the base classes: a
sport that does not opt in has none of this code in its MRO.

CelebrationMixin (afl, nrl, soccer, football)
The two lineages spelled this differently -- _check_for_goal /
celebrate_opponent_goals vs _check_for_score / celebrate_opponent_scores
-- but the bodies were identical apart from three things, each now a
seam rather than a branch:
  - wording -> score_phrase() / win_phrase() hooks
  - follow-up suppression -> COALESCE_SCORING_SEQUENCE, on for football
    where a touchdown lands as +6 then +1, off where two increments are
    two real goals
  - team identity -> _favorite_key, so nrl matches on team id without
    core learning why its abbreviations are ambiguous
Both config spellings are read, so a plugin adopting the mixin keeps
working with the keys already in its published schema.

Rotation strategies
The three "dialects" turned out to be one algorithm (SWRR) in two
shapes: an incremental picker holding state across calls, and a
precomputed per-cycle list. They agree within a cycle and differ only at
the boundary, so core ships both behind a name registry rather than
declaring a winner. weight_for is supplied by the host, so rotation.py
never learns what a favorite is; an unknown name degrades to "simple"
because it arrives from user config.

Each strategy is checked against a verbatim transcription of the plugin
code it replaces, over every live-game shape up to four games -- the
differential B5 will delete the bundled copies on the strength of.

185 new tests. Gates: 648 core unit, 60 plugin safety.

"""Opt-in capabilities for the sports scoreboards.
Each module here is a feature that only *some* sports want. They are composed
by inheritance (mixins) or selected by name (strategies) — never enabled by an
``if self.<feature>_enabled:`` branch inside the base classes.
The distinction matters: hockey has no celebrations, so ``HockeyLive`` does not
inherit :class:`~.celebrations.CelebrationMixin` and the celebration code is not
in hockey's MRO at all. A bug in it cannot reach a plugin that never opted in.
See ``docs/SPORTS_UNIFICATION.md`` for the full rationale.

"""Score / win celebration takeover — an opt-in capability.
Four of the nine scoreboards celebrate (afl, nrl, soccer, football); the other
five do not. This is a **mixin** rather than a flag inside ``SportsLive`` so the
five that do not opt in have none of this code in their MRO: a bug here cannot
reach hockey, and hockey's config never grows keys it ignores.
Usage — mix in *before* the mode class so its ``display`` runs first::
class SoccerLive(CelebrationMixin, SportsLive):
def score_phrase(self, points, team_abbr):
return secrets.choice(("GOOOOAAALLL!", f"{team_abbr} SCORES!"))
The two lineages spelled this differently (``_check_for_goal`` /
``celebrate_opponent_goals`` in the soccer lineage, ``_check_for_score`` /
``celebrate_opponent_scores`` in football) but the bodies were identical apart
from three things, each of which is a seam here rather than a branch:
* **wording** — :meth:`score_phrase`, the hook football uses to say "TOUCHDOWN"
from the points delta and soccer uses to say "GOOOOAAALLL";
* **follow-up suppression** — :attr:`COALESCE_SCORING_SEQUENCE`, on for football
where a touchdown lands as +6 then +1 a few seconds later, off elsewhere where
two quick goals are two real events;
* **team identity** — matching goes through ``_favorite_key``, so nrl can match
on team id (its abbreviations are ambiguous) without core knowing why.
The config keys are read under both spellings, so a plugin adopting the mixin
keeps working with the ``*_goals`` keys already in its published schema.

"""Live-rotation strategies — which live game to show next.
The nine plugin copies grew three spellings of this, and the survey behind

Round-Robin algorithm in two shapes:
* an **incremental picker** that holds weight state across calls and answers
"what next?" one game at a time (afl / nrl / soccer's ``_swrr_advance``), and
* a **precomputed cycle** that returns a full list of game ids up front
(football / baseball / basketball's ``_build_weighted_schedule`` and hockey's
``_build_rotation_schedule``, which differ only in loop shape).
They agree *within* a cycle — SWRR is deterministic — and differ only at cycle
boundaries, where the incremental form has no seam and the precomputed form
restarts. That is a real behavioral difference, so core ships both rather than
declaring a winner, and a plugin picks one by name:
self.rotation = get_rotation_strategy("swrr", weight_for=self._live_weight)
