Add geocode search and prevent parquet commits

[rdhyee]

Summary

Two quality-of-life improvements for the Cesium tutorial:

1. Geocode Search Box - Direct navigation to any location
2. Gitignore Update - Prevent accidental commit of large parquet files

1. Geocode Search Feature

Users can now paste a geocode PID into a search box and jump directly to that location:

How it works:

• Search box appears at top of page (below parquet source input)
• Enter/paste any geocode PID (e.g., geoloc_04d6e816218b1a8798fa90b3d1d43bf4c043a57f)
• Press Enter or click Submit
• Camera flies to location (2-second smooth animation)
• Automatically loads all data for that location

Benefits:

• No manual map clicking or searching
• Direct access to known geocodes from documentation/papers
• Enables reproducible demonstrations

Test examples:

• geoloc_04d6e816218b1a8798fa90b3d1d43bf4c043a57f (PKAP, 5 samples)
• geoloc_7a05216d388682536f3e2abd8bd2ee3fb286e461 (Larnaka, 0 samples)

2. Parquet Files in Gitignore

Prevents accidental commit of large data files:

• Added *.parquet to .gitignore
• Protects against committing 691MB oc_isamples_pqg.parquet
• These files should remain external (HTTP URLs or local caching)

Changes

• tutorials/parquet_cesium.qmd:
  • New search input box (line 40-48)
  • Reactive search handler with camera flyTo (line 628-664)
  • Database lookup + automatic query triggering
• .gitignore:
  • Added *.parquet pattern

Testing

• Search box renders correctly
• Valid geocode IDs fly to location and load data
• Invalid IDs log warning (no crash)
• Parquet file no longer appears in git status
• Preview tested locally
