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.)
