§Rill Patchbay — Event routing and automation

rill-patchbay is the evolution of rill-automation from version 0.2.0, merged with the mapping functionality from rill-control.

§Core components

Automata — generative signal sources (LFO, envelopes, sequencers)
Servos (in the control module) — connect automata to node parameters
Mappings — connect external events (MIDI/OSC) to parameters
Sensors — event sources from the external world
Manager — central coordinator for dual-thread architecture
