v1.0.3

🐛 Fixes

• @weave-framework/nx works with nx g / target inference again. The plugin's exports map didn't expose
  ./package.json, so Nx — which resolves @weave-framework/nx/package.json to discover its generators — failed
  with "Package subpath './package.json' is not defined by exports". Added "./package.json" to the exports map
  (and, defensively, to every @weave-framework/* package) so the manifest is always resolvable. A regression test
  now pins it.
• Fixed stale "pre-1.0" copy in the Installation and Quick start docs — Weave is 1.0.
