feat: Add updater prop, refactor types, tighten docs and build (#372) (#573)

Adds an `updater` prop to P5Canvas that lets users bridge React state
updates from within the p5 lifecycle without leaking React concerns
into sketch logic.

Type system refactor:
- Introduce P5CanvasInternalProps to cleanly separate component
  props from user sketch props
- Use destructuring instead of withoutKeys for prop separation
- Remove React.lazy for P5CanvasWithSketch (direct import preserves
  generic type flow)
- Remove generics from internal components (only needed at the
  public API surface)
- Delete InputProps, P5CanvasPropsWithSketch, WithChildren, and
  withoutKeys as they are no longer needed
- Remove boxed primitive instanceof checks from logErrorBoundaryError

Docs:
- Merge duplicate TypeScript examples into single examples with notes
- Collapse advanced topics into details blocks
- Remove buggy falsy guards from updateWithProps examples
- Fix error UI example to use unknown instead of any
- Fix example sketches link to use main branch

Build:
- Remove dead esbuild config, Vite 8 uses OXC by default
- Split p5 into its own chunk in the demo build via manualChunks
