v0.9.0: Replays and the chemical warfare pass

The simulation becomes deterministic, which makes recorded runs replay exactly. Meanwhile the field fills with chemistry: caustic clouds, hungry nanites, and vapor you can finally see through.

Added

• Deterministic simulation: the game now runs on a fixed timestep with split RNG streams, so recorded runs replay exactly
• Replay your recorded runs, complete with DPS tracking. Replays store only your decisions, keeping them tiny.
• Flak batteries leave a damaging caustic cloud where their shells burst
• Nanite swarms now eat the hull as damage over time
• HUD synergy readout during runs
• Gallery stats are level-aware, with level sliders on demos
• Supply crates are marked with their payload
• Run telemetry collection

Balance

• Cloud synergies no longer consume the vapor bank when they trigger
• Balloon mine blast radius reduced from 95 to 70 px
• Nanite vulnerability and spread now scale
• Seekers turn tighter
• Gravity wells are smaller

Visual

• Vapor clouds flattened to a uniform transparency and made far more see-through. Boss guns no longer punch through them visually either.
• Flak clouds read as smoke puffs instead of a symmetric disc
• Mine arming is now readable at a glance
• Every gallery demo sits on a hot-pink backdrop so effects read clearly

Fixes

• Replays of records made before the determinism overhaul froze the game. They now degrade to stand-ins and wear a badge marking them as legacy.
• Gravity Fuze arms only after the shell clears the muzzle
• The Revolver boss dies when its bar actually fills, and regrown guns properly add HP
• Gravity wells no longer drag the guns off bosses
• Fixed an admin page crash, added an Admin nav dropdown
• Fixed audio asset paths and a crash when refreshing the game page
• Dropped filler descriptions from the options rows
