WEATHER v295 REALISM IMPLEMENTATION MATRIX

A-F remain from v294:
A atmospheric simulation, B wind, C clouds, D thunderstorms, E supercells/mesocyclones, F tornado formation/lifecycle.

G Tornado motion: G1-G7 implemented.
H Tornado wind field: H1-H8 implemented.
I Tornado damage: I1-I12 implemented.
J Tornado debris: J1-J10 implemented.
K Rain: K1-K9 implemented.
L Snow/sleet/freezing rain/blizzards: L1-L8 implemented.
M Hail: M1-M8 implemented.
N Lightning/thunder: N1-N11 implemented.
O Hurricanes: O1-O15 implemented.
P Flooding: P1-P12 implemented.
Q Wildfires: Q1-Q15 implemented.
R Radar: R1-R14 implemented.
S Tornado tracker/ETA: S1-S10 implemented.
T Forecasts: T1-T10 implemented.
U Weather instruments: U1-U10 implemented through the station, wind meter, radar, and drone network.
V Warning sirens: V1-V7 implemented.
W Audio: W1-W10 implemented using existing imported OGG slots and vanilla sounds; no copyrighted audio is bundled.
X Visual effects: X1-X10 implemented using current particles and local effects.
Y Seasons/environment: Y1-Y8 implemented. Vanilla leaf blocks are not forcibly replaced; seasonal foliage progression affects environmental behavior and leaf-fall timing without destroying builds.
Z Player survival: Z1-Z10 implemented and individually toggleable with /weather:realism.
AA Missions/storm chasing: AA1-AA8 implemented.
AB Performance realism: AB1-AB8 implemented, including spatial indexing, adaptive schedules, deferred work, deterministic state, pooling, device limits, and warnings.

Commands added:
 /weather:realism on
 /weather:realism off
 /weather:realism status
 /weather:archive
