fix(game3): battle animation timing, RNG parity, pokedex habitats, multichoice UI and overworld events

- Battle Animation Pipeline: * Eliminate 90-frame audio polling stall in anim_vm end/waitsound opcodes, allowing attack animations to transition instantly into target hit flicker and HP bar drain. * Correct visual task counting in AnimVm:visualCount to match pret gAnimVisualTaskCount. * Signal bg task completion on restorebg (vm.args[7] = -1). * Fix termination conditions on shake tasks (ShakeMon, ShakeMon2, ShakeBattleTerrain), WaterSport droplet arcs, and StartSinAnimTimer. * Handle RGB555 color args in start_blend_anim_sprite_color and route P.destroyTask to AnimTasks.destroy. - RNG System & Seeding Parity: * Replace math.random in Party.giveMon with Rng.Random32() for personality values and Rng.Random() for IV bitfield extraction (HP/Atk/Def/Spe/SpA/SpD) matching GBA format. * Seed RNG on Title Screen A/Start press via Rng.seedNewGame() (matching SeedRngAndSetTrainerId) and perturb RNG state on title menu inputs. * Route NPC overworld idle/wander timers and wild encounter slot rolls through Rng.compat. - Pokédex Habitat & Area Maps: * Fix encounter tables extraction and map indexing to resolve Pokemon habitat locations across Kanto/Sevii maps rather than showing Area Unknown. * Render steady semi-transparent red overlays for Pokédex area map locations. - Multichoice Menus & UI: * Implement multichoice table extraction and data population for Viridian blackboard status ailments and special dialog interactions. * Improve choice box borders, pagination, and Town Map wall viewing. - Overworld Events & Flags: * Fix Route 1 entrance girl NPC spawning and script triggers after starter selection. * Ensure consistent save reload state in Oak's Lab.
