Add crash_strikes and cooldown_until columns to bots table. Worker
increments strikes on crash (cooldown at 3), resets on success.
Matchmaker excludes cooldown bots from pairing, series scheduling,
and championship brackets. Fix erroneous cooldown filter on series
table in finalizeCompletedSeries (column only exists on bots).

Collect GameState snapshots during match execution (one per turn), then
run 100 random-play rollouts per snapshot post-match to compute per-turn
win probabilities and detect critical moments (|delta| > 0.15). Results
are stored in the replay JSON as win_prob and critical_moments fields.

Replace broken Taylor series sin/cos approximations with math.Sin/math.Cos
in both engine/match.go and cmd/acb-mapgen. The Taylor series produced
incorrect results for angles > π, causing wrong positions in 3+ player maps.
Upgrade map generator wall placement from random scatter to cellular
automata (B5/S4 rule, 4 iterations) with rotational symmetry enforcement
and connectivity validation. Add comprehensive mapgen tests and dominance
win condition tests.
