Breaking API changes in geobuf 3.x: - geobuf.featureToGeobuf(f).toBuffer() → Buffer.from(geobuf.encode(f, new Pbf())) - geobuf.geobufToFeature(buf) → geobuf.decode(new Pbf(buf)) Added pbf ^3.3.0 as a new dependency (required by geobuf 3.x API). Updated all source files and tests to use the new API. Some tests still fail due to behavioral differences in geobuf 3.x output format (empty properties handling, numeric ID preservation).

- Add lib/geobuf-helpers.js with centralized encode/decode functions - normalizeFeature ensures backwards compatibility: - Adds empty properties object (geobuf 3.x omits them) - Converts numeric IDs to strings (geobuf 3.x preserves numbers) - Update all decode/encode calls to use shared helpers - Update test expectations for: - More compact encoding sizes (geobuf 3.x is ~50% smaller) - Different minzoom/maxzoom values (derived from sizes) - Changed pbf error message for corrupt data Note: getDatasetInfo() minzoom/maxzoom values will differ after upgrade due to more efficient encoding. This affects zoom recommendations only, not feature storage or retrieval. Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>

This upgrades the geobuf dependency used by the v2x branch (which is currently still used instead of the latest v3 in some cases).
While this addresses some vulnerabilities in subdependencies, it unfortunately results in some changes to
cardboard's behavior--in particular, due to somegeobufencoding efficiency gains, minzoom/maxzoom calculations are different.I've punted for now on evaluating the downstream implications of this change, but wanted to push this up as a draft PR so we can evaluate those implications.
