### Is your feature request related to a problem or challenge? Follow-up to #5125. This issue captures the remaining implementation work identified after the original module extractions. Previous work extracted list, decimal, dictionary, string, map, run-array, and union functionality into private submodules. However, `arrow-cast/src/cast/mod.rs` still contains several cohesive groups of implementation helpers around the top-level cast kernel. This makes the module harder to navigate and leaves additional opportunities to continue the functional separation started by #5125. ### Describe the solution you'd like Move the remaining cohesive implementation helpers into private submodules while retaining `cast_with_options` as the centralized top-level dispatcher. Potential groups include: - [ ] Temporal helpers for timestamps, dates, durations, intervals, and timezones - [ ] Numeric and boolean conversion helpers - [ ] Binary, fixed-size binary, and byte-view conversion helpers - [ ] Struct conversion helpers - [ ] Remaining decimal adapters, including integer-to-decimal and generic decimal routing helpers These groups can be extracted in separate PRs linked to this issue. The extractions should: - Avoid behavioral changes - Preserve existing public API paths - Re-export public helpers already used by other workspace crates - Keep the top-level source/target dispatch centralized - Keep individual PRs small enough to review independently ### Additional context Related extractions include #5537, #5552, #5555, and #5563. Together with the separate test-reorganization follow-up, this issue supersedes the remaining work under #5125 and allows that umbrella issue to be closed. ### AI usage disclosure This issue was drafted with assistance from OpenAI Codex. Codex was used to inspect the existing `arrow-cast` module structure and the changes made by related PRs. No code changes were generated or made. -- This is an automated message from the Apache Git Service.
