Woodlighting Standards

• Added deterministic fire placement, spread, and burn-away (fully replaces vanilla fire RNG near portals)
• Added canonical position keys so mirrored/rotated setups produce identical fire timing
• Replaced tick-based timer with cumulative probability tracking The old formula:

ticks = -ln(1-u) / probability

The new formula:

target = -ln(1-u)
portal lights when cumulative >= target
where cumulative += probability each tick

Basically the current setup gives a certain amount of progress to the total, with better setups giving more.

• Added vanilla fire suppression in portal subchunks to prevent RNG interference
• Added lit portal detection so fire ticks and scanning stop once the portal is lit (saves performance)
• Added chunk unload pause so timers don't advance when chunks aren't loaded
• Full save/load persistence for scheduled fires, burn-aways, counters, and portal state
• Debug HUD now shows cumulative progress, ETA, and scheduled fire/burn counts
• Manual lighting (flint & steel) now works normally inside tracked/ticked portal frames
