Refactor src/github/result-handler.ts to consolidate duplicated post-processing logic into a single pipeline. There are currently overlapping paths for workflow/image cleanup and change filtering, plus helpers that are defined but unused. Create one canonical processing flow that applies cleanup and filtering in one place, remove dead helpers, and ensure all callers use the same path. The goal is to reduce drift between result paths, make future changes safer, and clarify exactly how Codex outputs are transformed before publishing.
