[codex] Phase 3: add globe URL params and multi-term search

[rdhyee]

Summary

Implements issue #156 Phase 3 on top of the merged Phase 1 work.

• adds query param read/write for q, sources, material, context, object_type, maxSamples, view, and perf
• hydrates search and filters while preserving existing hash camera/sample state
• folds in multi-term AND search with relevance ordering using the globe page query style

Verification

• quarto render tutorials/progressive_globe.qmd
• git diff --check

Draft because phases 2, 3, and 4 are parallel PRs and may need final integration ordering.

Review finding: ?q= is restored into the search box, but the search is not executed on page load. A shared URL like ...?q=pottery%20Cyprus renders the input value while leaving the results panel unchanged until the user manually clicks Search or presses Enter. For the URL params + multi-term search behavior, the visible search state should be restored automatically.

Addressed in c06dd02: restored ?q= searches now run automatically after the search handlers are bound, so shared query URLs populate the visible results without requiring a manual Search click.
