Implements the v1 direction decided in the RFC as a set of `x` subcommands
plus a small, contained compiler change.

  * URL-as-identity, no registry — a dependency is named by its git import
    path and a `git tag vX.Y.Z` publishes a version.
  * Minimum Version Selection — a `require` is a minimum; the resolver picks
    the greatest required minimum per module, then the reachable closure at
    those versions. Deterministic, no SAT solver (tools/x/pkg.ludic).
  * Content-addressed global store + per-project links — packages live once in
    ~/.ludic/store keyed by a content hash; each project links them under
    ludic_modules/. package.ludic (manifest) + package.lock.ludic (lock).
  * Namespace registration for source packages via a module-root import
    fallback in the compiler: do_import resolves a non-local, non-absolute
    import under $LUDIC_MODULES (default ludic_modules/), so a fetched
    package's Ludic compiles into the consumer the way the built-in stdlib
    does. Collisions and missing prebuilt targets are hard errors.

Commands: x add / x get / x update / x verify / x vendor. New hermetic suite
`x test-pkg` (stands up throwaway git repos, offline) is gated inside `x test`.

Existing programs compile byte-for-byte identically (the import fallback only
fires when the local path is absent); the C-free bootstrap fixpoint holds and
the seed is regenerated. Full suite: 87 passed, package suite: 12 passed.

# package manager (issue #63): the per-project linked view into the global
# content-addressed store, and the optional hermetic copy from `x vendor`. Both
# are regenerated by `x get` / `x vendor` — package.ludic + package.lock.ludic
# are the tracked source of truth, so these stay out of the tree.
