- runtime/engram.el: thin El wrappers over all __engram_* and __generate
seed primitives (16 functions), matching the el_seed.c API exactly
- runtime/manifest.el: build manifest documenting module load order and
the cat+compile+cc command for runtime builds
- el-compiler/src/codegen.el: add 77 __-prefix seed primitive entries to
builtin_arity, covering str, fs, http, thread, exec, env, time, uuid,
math, state, html, json, and engram seeds
