W0 symbolica lane: session, comparison, locked-build and devmain-merge scripts

socket1_ab_session.sh runs the C-4L and C-5F A/B under the socket-1 lock;
compare_all.sh runs strict record comparisons against ref-r1;
build_locked.sh/build_devmain.sh wrap cargo in the shared build lock (the
latter builds against a trial Symbolica tree via cargo --config patch
overrides); devmain_merge.sh reproduces the dev+main trial merge.
