[PR] feat(go): expose string and range predicates through the Go binding [paimon-rust]

["jackylee-ch (via GitHub)" <gi...@apache.org>]

   The Go `PredicateBuilder` exposed only `Eq`/`NotEq`/`Lt`/`Le`/`Gt`/`Ge`/`IsNull`/`IsNotNull`/`In`/`NotIn`, so a Go caller could not push down `StartsWith` / `EndsWith` / `Contains` / `Like` / `Between` / `NotBetween`. `Contains`, ends-with, and a leading-wildcard `LIKE` cannot be expressed with the available range operators, so those filters read the whole table back and discard rows in Go, skipping no files. The C binding (#523) and the Python binding already expose all six.
   
   This adds the six methods, wiring the already-exported `paimon_predicate_*_with_case_sensitive` C functions through the existing FFI helpers: starts/ends/contains reuse the leaf-datum shape, `like` adds the escape char, and between/not-between pass the two bounds. All honor the builder's case sensitivity.
   
   A test exercises each operator against `simple_log_table` and asserts the matched rows.
