Chris Tsang 601447af6c Depend on published visioncortex 0.9.0; simplify CI
visioncortex 0.9.0 is on crates.io, so the workspace now uses the registry
version instead of the local `../visioncortex` path (a [patch.crates-io]
example is left in a comment for local visioncortex development).

CI no longer needs the adjacent visioncortex checkout / published-crate caveats:
rust.yml, python.yml, and release.yml build from a single checkout.

Chris Tsang 749f0df0bd Add nodejs: WebAssembly Node package with no native dependency
New nodejs/ package: a wasm-bindgen crate (vtracer-wasm) built with wasm-pack
that wraps the vtracer framework, plus a thin JS layer for file I/O. Image
decoding (png/jpeg/gif/bmp via the image crate) runs in wasm too, so the
package has zero native dependencies — no sharp, no node-gyp.

No separate general-purpose wasm crate: the Node package directly owns and
wraps the wasm. Excluded from the cargo workspace (wasm-bindgen cdylib), built
with wasm-pack.

JS API (camelCase options): convertBuffer, convertPixels, convertFile,
convertFileSync — each taking an Options object (preset, colorMode,
hierarchical/cutout mosaic, mode, palette, maxColors, optimize, ...). Ships
index.d.ts types and a node smoke test. README updated.

Verified: builds to wasm32-unknown-unknown; `node test.js` passes; output
matches the CLI/Python bindings (253 paths on the tank sample).

Chris Tsang f76aed78b2 Add vtracer-py: Python bindings with a rich API
New crates/vtracer-py (pyo3 + maturin, abi3) wrapping the vtracer framework.
Rather than a thin CLI-style wrapper, it exposes a mutable `Config` class with
named properties and `bw`/`poster`/`photo` preset constructors, plus three
input paths — `convert_file`, `convert_bytes` (encoded image, optional format),
and `convert_pixels` (raw RGBA8) — available as `Config` methods and
module-level functions. Palette is a list of `#rrggbb` strings; bad inputs
raise ValueError.

The core crate stays pure: image decoding lives here. The crate is excluded
from the cargo workspace (pyo3 extension-module cdylibs don't link libpython,
which breaks `cargo test` at the root) and is built with maturin. Ships a
vtracer.pyi type stub. README updated.

Chris Tsang 660dc4ff93 Remove the 0.6.x cmdapp crate
Superseded by crates/vtracer (framework) + crates/vtracer-cli. Verified the
new pipeline reproduces cmdapp's geometry and colors byte-for-byte (PNG always;
JPEG once the image-crate decoder is held constant), so the old crate is
retired. Drop its now-stale workspace exclude entry. Git history preserves it.

Chris Tsang e46c971845 Rewrite into a vectorization framework (pillars 1–4)
Replace the 0.6.x single-pipeline crate with a stage-based framework, per
docs/design/. Implements Motivation pillars 1–4 (frontend, curve fitting,
color fitting, optimizer); mosaic (5) and bindings are deferred.

Workspace:
- crates/vtracer      — the framework library (wasm-safe, no I/O)
- crates/vtracer-cli  — thin CLI wrapper (clap 4 + image I/O)
- cmdapp/ and webapp/ excluded from the workspace (git-preserved)

Stages behind object-safe traits, composed by a Pipeline driver:
- Frontend: ColorClusterFrontend (+ transparency keying), BinaryFrontend
- CurveFitter: Pixel / Polygon / Spline (region tracing via visioncortex)
- ColorFitter: Identity, FixedPalette (OKLab-nearest), AutoQuantize
  (area-weighted median cut), MergeAdjacent
- OptimizerPass: QuantizePass, SimplifyPass
- SvgWriter: relative/absolute shortest encoding, H/V/S shorthands,
  compact number formatting, <g fill> grouping

visioncortex is a path dependency on the local 0.9.0 checkout.

Verified: 14 unit/integration tests pass; framework builds for
wasm32-unknown-unknown; CLI output renders faithfully via rsvg.

Evan Jones f4c7828049 Python bindings configured correctly for PyPI releases (#54)
* Python bindings sep 2023 (#52)

* Added maturin-based Python binding, to be deployed to https://pypi.org/project/vtracer/

* Removed poetry mentions from pyproject.toml, added README_PY.md for use on PYPI

* ->   v0.6.1
-> moved Python bindings to bottom of converter.rs

* - README_PY.md needed to be inside the cmdapp directory to display on PyPi.irg
->  v0.6.3

* Move code around

* Edit Readme

* Edit RELEASES.md

* Feature guard

* Build wheels with the cmdapp/Cargo.toml rather than top-level Cargo.toml

* use cmdapp/Cargo.toml for all Maturin CI actions, which causes Github to build all platforms python wheels and submit a new release to PyPI

* Bump to 0.6.4 for new PyPI release with all platforms' wheels included

* PyPI didn't accept a 'linux_aarch64' wheel for a release. For the moment, remove the platform until I can convince the action to build 'manylinux_aarch64' or the like

* Version bump while I work out CI & PyPI release wrinkles

* Maturin authors say `compatibility = "linux"` in pyproject.toml is causing PyPI failure. Replacing with "manylinux2014"

* bump to v0.7.0 in preparation for release from original vtracer repo
