Walks through the full helper evolution pipeline (QEMU C ->
original IR -> full -> to-inline -> declarations-only), covering
env-to-CSV rewriting by fix-helpers, REVNG_INLINE/REVNG_EXCEPTIONAL
semantics, CSV access metadata, and per-artifact usage (lift,
enforce-abi, recompile).
All code snippets are tested via revng test-docs.
