State

Hello-world for #[derive(State)] — the per-instance non-numeric data plumbing.

Source: examples/truce-example-state/.

#What it demonstrates

• The split between params (numeric atoms — automatable, host knows about them) and state (anything else — strings, file paths, view modes, nested structs — the framework round-trips bytes on save_state / load_state but the host never sees the shape).
• #[derive(State)] on a StateBinding-bound struct.
• A custom egui editor that reads + writes the instance label.
• An audio-thread param (Active: BoolParam) sitting alongside the state-only label.

#Parameters
