1.0.0-alpha.1 - 2026-07-24

Ground-up rewrite of VTracer into a vectorization framework with pluggable stages.

Added

Pluggable pipeline: swappable frontend (segmentation), color fitting (incl. custom palettes), curve-fitting backend, and an optimizer pass phase.
Mosaic mode: true seam-free, gapless tessellation via shared boundary-graph tracing (pixel, polygon, and spline fitters), replacing the old "cutout" that produced seams.
SVG optimizer: relative path syntax, shorthand commands, and coordinate-precision reduction for smaller files.
@visioncortex/vtracer Node.js package (npm): wasm core with a native image reader.
Rewritten Python bindings (vtracer-py) with a richer API; pyo3 bumped to 0.26 (fixes CPython 3.14 segfaults, #124).
CLI accepts positional input/output arguments (#114).

Changed

Workspace restructured into crates/vtracer (core lib), crates/vtracer-cli, crates/vtracer-py, and nodejs/.
CLI upgraded from clap 2.x to 4.x (#118).
filter_speckle CLI cap raised from 16 to 128, matching the web app (#115).
Depends on visioncortex 0.9.
Python wheel CI now runs only on release tags and manual dispatch, not on every commit.

Removed

The pre-1.0 cmdapp crate and the demo webapp GUI.
