Phase 1a used `git submodule foreach`, which only visits initialized
submodules — a fresh machine silently skipped population while the script
still reported success. It now explicitly inits + populates each submodule
declared in .gitmodules (inheriting credentials from the parent origin URL
so non-interactive init authenticates; .gitmodules stays credential-free),
then advances each to its remote branch tip. Reporting reflects the real
configured count.
Also removes the orphaned `projects/solverbot` gitlink (mode 160000),
committed without a .gitmodules entry, which made `git submodule status`
throw `fatal: no submodule mapping`. solverbot's own Gitea repo is untouched.
