El SDK CI - dev / build-and-test (pull_request) Failing after 13m17s
Establish lang/runtime/ as the ONE canonical el runtime (from the active runtime that carries hebb/emb persistence + the new WAL); repoint the el CI publish, engram build, elb default, and in-repo build scripts to it; delete the el-compiler/runtime + lang/releases/ forks; add scripts/check-single-runtime.sh drift guard. Fixes a live prod bug: the el CI published el-runtime-c/-h from the LAGGING el-compiler fork (0 hebb refs), so the shipped soul never persisted Hebbian edge weights — learned co-activation was wiped on every restart. Publishing from canonical ships the stranded 'learning that cannot outlive the process' fix. WAL storage engine + integrity fixes (DELETE->tombstone + store-layer protection, safe data-dir default) ride in behind ENGRAM_WAL (default off = byte-identical to today). Verified: engram elb per-module build clean, WAL gate 66/66, native smoke ok, drift-guard green.
