feature/jax: paper to its own PR (#562); drop ephemeral docs + unused configs

papers/post.md moves to feature/vpd-paper (byte-identical to the published
static.goodfire.ai source). AUDIT.md / REMAT_NOTES.md / INTEGRATION.md were
working documents that finished their jobs — live residue (open items, S24
pending decisions) folded into jax_single_pool/CLAUDE.md. Config cuts: the
_llama8b leftovers and the pile smoke pair (referenced by nothing; the test
fixtures and the pile production pair stay).
