Rewrite CLAUDE.md and README.md for post-split single-repo scope

LithosAnanke is now its own repository rather than a branch inside the
combined StarForth/LithosAnanke monorepo, so this drops the old
master(StarForth)/lithosananke(kernel) branch-topology framing in favor of
the current reality: this repo's master is the sole LithosAnanke production
line. Ground-truths numbers that had drifted (kernel tree file count,
word_source file count, capsule count), reframes the vendored VM source as
the embedded engine it actually is rather than a second production target,
and independently verifies the ACL kernel-parity and DoE-campaign claims
against the actual current code. Fixes README's self-referential
"see master branch" link to point at the separate StarForth repo instead.
