Restructure as monorepo: move container to subdirectory

Move .git/ to project root so the entire workspace is tracked in a
single repository. Git detects all container-root files as renames
into the container/ subdirectory. Root-level files (.github/,
LICENSE.txt, CLA.md, CONTRIBUTING.md, .gitattributes) remain at the
repository root. The docs/ package was already tracked at docs/ and
is unaffected by this change.

This is a structural reorganization — no code changes.
