Closes #11121. BYTE_STREAM_SPLIT previously used the page header count as its decode bound while deriving stream stride from the encoded bytes. A malformed header could therefore drive `join_streams_const` past the end of the buffer. This change derives the decoder value count from complete encoded values, rejects partial values and encoded counts larger than the declared page count, and leaves declared counts that include Parquet v1 nulls valid. Higher-level readers now return their existing insufficient-values error for truncated required pages instead of panicking. Tests cover the reported declared-count mismatch, partial values, and impossible oversized buffers. Validation: - `cargo test -p parquet --lib` - `cargo clippy -p parquet --lib --all-features -- -D warnings` - `cargo +stable fmt --all -- --check` - `git diff --check` -- This is an automated message from the Apache Git Service.
