feat: enhance map renderer with catalog synchronization and reload functionality

- Added a "Reload Current Map" button to the left panel for refreshing the selected map after catalog edits.
- Updated catalog CSV handling to support non-authoritative `categorization` and `qualities` columns.
- Implemented automatic addition of newly observed shapes to the game catalog CSV during cache builds.
- Modified catalog entry handling to ensure proper boolean overrides for `roof` and `semitransparency`.
- Introduced `ensureShapeCatalogCoverage` function to maintain catalog integrity based on observed shapes.
- Enhanced the serialization of catalog entries to include new fields and proper formatting.
- Updated UI to reflect changes in reload state and button functionality.

 - inspect mode lets you pin a shape tooltip, hide a single instance, and restore hidden instances from the left panel
 - PNG export is generated in the browser from the cached scene instead of being rasterized server-side
 - hidden instances can be exported as JSON and each catalog CSV can be downloaded from the viewer
-- catalog CSV rows support `roof` and `semitransparency` boolean overrides; leave them blank to use decoded defaults, or set `true`/`false` per shape
+- the left panel includes a `Reload Current Map` button that forces a fresh rebuild/load of the currently selected map after catalog edits
+- catalog CSV rows support `roof` and `semitransparency` boolean overrides; the catalog is authoritative for those properties, so blank means `false` and only explicit `true` turns them on
+- cache builds automatically add any newly observed shapes into the matching game catalog CSV without overwriting existing rows, then rewrite the file sorted by `shape_code`
+- catalog CSV rows also support non-authoritative `categorization` and `qualities` columns; cache builds auto-fill them when blank from the existing derived categorization and observed per-shape quality values
