refactor(lib): remove dead export-env blocks (ADR-025 blocker 4)

Two export-env blocks in lib_provisioning/ ran at module load time as side
effects of the lib_provisioning/mod.nu star-import chain. ADR-025 empties
that chain; the side effects were never going to fire again and neither has
a remaining reader that depends on them.

1. lib_provisioning/cmd/env.nu
   Former block: called check_env (a pre-flight gate for PROVISIONING_VARS /
   PROVISIONING_WORKSPACE_PATH / PROVISIONING_WK_ENV_PATH existence) and set
   $env.PROVISIONING_DEBUG = false. Nobody imports cmd/env.nu directly; every
   downstream reader of PROVISIONING_DEBUG either sets it explicitly via a
   --debug flag branch or reads it with `?` + default fallback.

2. lib_provisioning/providers/registry.nu
   Former block: $env.PROVIDER_REGISTRY_INITIALIZED = false. The four read
   sites in registry.nu already use `$env.PROVIDER_REGISTRY_INITIALIZED? |
   default false`; the unset state is equivalent to false. Zero behaviour
   change.

Both files now carry a comment explaining the removal so future contributors
understand the history without reading ADR-025.
