refactor: split lib.rs into params and editor modules

Move parameter structs, defaults, and build_settings into src/params.rs; move the egui editor into src/editor.rs. lib.rs now holds only the plugin shell, DSP wiring, and process(). No behavior change (16/16 tests pass). Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

+//! egui editor.
+//!
+//! Placeholder layout for now — Stage 6 replaces it with meters, gain-reduction displays, a
+//! gain-curve view and draggable crossover handles. Built to stay usable meanwhile: a resizable
+//! window with a vertical scroll area so every control is reachable at any window size, global
+//! controls in a label|slider grid, and the four channels (low/mid/high/all) side by side.
