Add portable prototype explorer with browser inference and GBIF integration

[asgersvenning]

Adds the prototype explorer and its static browser distribution, including ONNX inference with preclassification embeddings and insertion of new images into the fixed t-SNE map. The current UX increment groups controls into Explore, Predict and Settings, uses one model-scoped GBIF namespace setting, resolves names/photos directly in the browser, and shows attributed reference photos for predicted species. Optional resumable GBIF name snapshots can be embedded in the artifact.

Original class IDs/order, prediction semantics and existing projection coordinates are preserved. Legacy saved views migrate to the shared setting; generic IDs and synthetic cases avoid GBIF calls. Local Python launcher endpoints remain compatible, but names/photos no longer require them. The existing public production release is unchanged.

Validation:

• Current increment: 16 affected Python tests; static lint, formatting and import contracts; installed-wheel smoke and explicit GBIF asset packaging check.
• Chromium: 158 retained interaction assertions and 16 focused portable-UI checks; live GBIF name/image access from plain static hosting.
• Actual browser inference: 15 prediction rows, 1280-dimensional embedding and unchanged fixed-map query coordinates. Desktop/mobile previews use real predictions and credited species photos.
• Shared-client failure checks cover cancellation, bounded requests, cache, malformed responses, offline/429/timeout behavior, taxon identity and attribution.

See dev/prototype_space/portable-qualification.md for evidence and reproduction. Qualification targets Chromium/WASM; other browsers, WebGPU, complete offline image distribution and browser-side construction of global diagnostics remain roadmap work. The candidate includes a partial 100-taxon snapshot; the helper resumes missing lookups. Human layout review and PR review are pending.

The branch includes current local master 268d294 through a merge, with agent workflow guidance in a separate agent: commit.
