…acebookincubator#759) Summary: CLI tool to evaluate Nimble encoding sizes on real column data. Loads int64 values from CSV, encodes with each supported encoding+compression combination via `EncodingFactory::encode()`, and reports serialized sizes. Supports forced encoding trees via `ReplayedEncodingSelectionPolicy` (e.g., `Dict[Trivial{C}[FBW{C}]]`) and auto-selection via `ManualEncodingSelectionPolicy`. Usage: `buck2 run fbcode//dwio/nimble/tools/encoding_bench:encoding_bench -- values.csv` Reviewed By: srsuryadev Differential Revision: D105891481
