Adds a lantern sprite sheet (art/textures.py writes lantern.png: an unlit cell, then flame frames). The valley draws a beacon counter in the top right as three Lua screen sprites: a Tally object's onUpdate polls the beacons mask and plays flame or dark per lantern. The title menu cursor is now a UI image showing the unlit cell.

lighthouse.lua starts the credits from the finale's onComplete (psxsplash#86), and CI moves to splashedit-ng 54392a4 and psxsplash 1e4c331. features.json goes to phase 7 with sprites (spriteAnimCount) and ui-sprite (the --stats image line).
