Normalize ammo economy: per-weapon refill, stream drain, behavior fixes

Browse Source 
- Every special weapon gets an explicit 'refill' (units per ammo pickup,
  tuned so one pickup funds ~10 kills) replacing the ammoRefillFraction
  log2 heuristic and ammoWeight overrides
- Bile Blunderbuss + The Cauterizer join Red Right Hand as time-denominated
  stream weapons ('drain' per second) instead of per-shot cost
- Sawblades ricochet through enemies (bounce fix), traps catch 3 victims,
  lobbed projectiles arc overhead and always trigger at the target point
  (Flesh Masher / Trap Queen / Swarm Jar payloads now actually deploy)
- Boss rooms stock one ammo on entry and drop one guaranteed on death
- Cauterizer burn trimmed (2.2s x2 -> 1.5s x0.8), bile acid pools trimmed
  (3.5s x1.5 -> 2.5s x0.8), Marrow Draught now covers stream drain
- New tools/ammo_sim.js calibrates every weapon into the 8-13 kills/refill
  band (all 15 pass); smoke test guards the ammo structure
- v0.3.0, cache bump v=44

// Ammo economy: `ammo` is the magazine (trigger-time / burst feel), `refill`
// is what one ammo pickup hands back (~10 kills' worth). Sustained-stream
// weapons use `drain` (ammo per second while held) instead of per-shot cost.
// Calibrated with tools/ammo_sim.js — every weapon should land ~8-13 kills
// per refill at base stats.
