This PR was originally a part of https://github.com/zed-industries/zed/pull/53551 so theres more info about its motivation there. - Add a CharBag prefilter on path candidates to skip irrelevant entries before invoking nucleo's matcher. - Use binary_search on sorted matched char indices when reconstructing byte positions (perf improvement). - Add a criterion benchmark comparing `fuzzy_nucleo` path matching against the existing fuzzy crate.
