Fizlet 0.2.0

E2, the first bricks (the ones Battlefield Blitz needs):

• fizlet/input: keys → intents with one-frame edges latched in the read phase, pointer, a touch stick, on-screen press(); keys typed in the host's fields never count.
• fizlet/collide: fixed-capacity spatial hash (add / near take typed arrays and indices so nothing boxes), overlap, circles, circleRect, inRect, swept segCircle.
• fizlet/fx: pooled particles (struct of arrays), the hero blast(), pop words, scorch, shake.
• fizlet/sound: the event ring → synth cues adapter (or your own player); gesture unlock.
• fizlet/embed: palette (hex only), easter-egg triggers (sequence, gesture, click; desktop / mobile scope), lazy load, the open / close toggle, Escape to close.
• Tests for every brick (Node and Chromium); budgets in CI.
