Subject: [PATCH] fix: prevent bigint precision loss in structured filter value
 parsing

When parseFilterValue converts numeric strings to JS Number, integers
exceeding Number.MAX_SAFE_INTEGER lose precision (e.g. 2062449923745665025
becomes 2062449923745665024). Keep them as strings so the Rust backend can
parse them exactly via serde_json::Number.
