siplot 0.1.0

//! siplot — silx-style scientific plotting on top of egui + wgpu.
//!
//! See `doc/design.md` for the design. The layering mirrors silx's
//! `BackendBase ↔ BackendPygfx`:
//!
//! - [`core`]   — the `Plot` model + `Backend` trait + shared types (Transform/Colormap …)
//! - [`render`] — the wgpu renderer (`egui_wgpu::CallbackTrait` impl), owns GPU resources
//! - [`widget`] — high-level plotting widgets plus [`PlotView`] for chrome + interaction + paint-callback registration
//!
//! Current scope: vertical slice 1, steps 1–5 — a wgpu data layer (clear,
//! colormapped image, polyline curve) under egui chrome (frame, grid, ticks,
//! tick labels, colorbar), all sharing one coordinate transform.
