Add per-key segment build observability for OPEN_STRUCT columns. ## What Seven metrics covering type failures and dense/sparse classification: **Meters** (per table/column/key): - `OPEN_STRUCT_TYPE_COERCION_FAILURES` — value dropped due to type coercion failure (was global, now per-key) - `OPEN_STRUCT_TYPE_INFERENCE_FAILURES` — entry dropped because Java type couldn't map to Pinot DataType **Gauges** (per table/column, emitted at seal): - `OPEN_STRUCT_DENSE_KEY_COUNT` - `OPEN_STRUCT_SPARSE_KEY_COUNT` - `OPEN_STRUCT_TOTAL_KEYS_DISCOVERED` - `OPEN_STRUCT_KEY_FILL_RATE` — per-key, 0–100% ## Tests Existing UTs are enough as there is no logic change here. -- This is an automated message from the Apache Git Service.
