Sister of `pulseCounter`: picks a random integer in [0, count) on each rising-edge `pulse`. Pair with `pulseRouter` for non-rhythmic dispatch where round-robin reads as too mechanical. Deterministic — uses a seeded mulberry32 PRNG so seek + replay produce identical sequences.

Use cases
- Random cursor / particle trail — feels less mechanical than round-robin since the same channel never reads as the obvious pattern.
- Sound sample randomization — pick one of N variation samples per trigger so repetition doesn't feel mechanical.
- Avoid-repeat dispatch — `avoidRepeat=true` ensures back-to-back pulses never hit the same channel.
Envelope
Use randomIndex as the node type inside a graph node envelope. Add id, optional params, optional connections, and optional activeWhen based on the guide context.
