test(stats): add e2e parquet-stats pruning test; harden starts_with binding Follow-up to @universalmind303's review of the starts_with stats-pruning PR. - e2e test (daft-parquet/src/helpers.rs): write a real two-row-group parquet file with per-row-group Utf8 min/max stats, then assert prune_row_groups() skips the right row groups for starts_with prefix predicates ("b" -> [1], "a" -> [0], "c" -> [], empty -> keep all). Exercises the production path (row_group_metadata_to_table_stats -> TableStatistics::eval_expression), not just the in-memory stats layer. Adds daft-functions-utf8 as a dev-dependency of daft-parquet. - named binding (daft-stats/src/table_stats.rs): bind starts_with args by name (input/pattern) via FunctionArgs::required instead of positional indexing, mirroring the kernel's own binding, so keyword args in either order work. Still fails safe (Missing) if an arg is absent. - helper boundary tests: increment_utf8_prefix / next_unicode_scalar surrogate skip (U+D7FF -> U+E000), char::MAX carry-left, and all-max -> None. Local: cargo test -p daft-stats (15 passed) and -p daft-parquet --lib helpers (1 passed); clippy --all-features --all-targets -D warnings, fmt, codespell all clean.
