Chris Tsang 58221025d5 Prepare 1.0.0-alpha.3 release 
- version 1.0.0-alpha.3 across the workspace, Python, and Node packages
  (and the vtracer dep pins, install snippets, and docs.rs link)
- CHANGELOG: date the section; note the new vtracer-bench crate and the
  watershed blurred-crack filament fix

(Supersampling was explored after alpha.2 and reverted -- it did not
improve output enough to keep.)

Chris Tsang 5743912da6 Trim image codec features in the CLI and Python crates 
vtracer only decodes input, but image's default features pulled a full AV1
encoder (ravif/rav1e) and OpenEXR into the CLI binary and the Python wheel.
Restrict to decode-only input formats (png, jpeg, gif, bmp, webp, tiff, ico,
pnm, tga, qoi). The release binary drops from ~3.23 MB to ~2.46 MB and builds
faster; supported inputs are unchanged in practice (avif decode was never in
image's defaults anyway).

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.
