fix(parsers): preserve format boundaries and query occurrence identity

Normalize parsed facts at their owning boundaries across PE exports and certificates, ELF section names, GPU bundles, IL2CPP generic types, dyld slice selection, source maps, environment replay, and JavaScript mapped arguments. Preserve partial facts and explicit unsupported cases; clarify the corresponding documentation.

Validation: 831 affected tests passed with one existing skip across 23 files; build, typecheck/lint, documentation, formatting, and 2133-file test discovery passed. Format controls are synthetic; real Unity, GPU, and ARM-device execution is unverified.
