keys.\n- `group_by` sorts and groups equal keys.\n- `unique` and `unique_by` remove structural or keyed duplicates.\n- `min`, `max`, `min_by`, and `max_by` return extrema, including `null` for empty

returns array indices for arrays.\n- `keys_unsorted` preserves object insertion order.\n- `has` tests object keys or valid array indices.\n- `in` reverses `has`.\n- `contains` and `inside` apply

occurrence searches, insertion-point binary search, generator-aware quantifiers, emptiness checks, and SQL-style `IN` functions.\n\n## Behavior\n\n- `indices` returns all matching string or array positions.\n- `index` and `rindex` return the first and last matching positions.\n- `bsearch` returns an index or jq's negative insertion-point encoding.\n- `all` and `any` preserve short-circuit

Scope\n\nThis feature implements jq's standard string manipulation filters using Unicode-aware codepoint handling where specified and ASCII-only case conversion for `ascii_downcase` and `ascii_upcase`.\n\n## Behavior\n\n- `trim`, `ltrim`, and `rtrim` use jq's defined Unicode whitespace set.\n- Prefix and suffix filters remove text only when the corresponding string is present.\n- ASCII case filters alter only ASCII letters.\n- `explode` converts strings to codepoint arrays and `implode` applies jq replacement behavior for invalid codepoints.\n- `split` returns an array;
