`_copy_core_inputs` listed `uv.lock` in the names its copytree `ignore`
drops, and copytree applies that callback at every depth, so the member
lock `pm/uv.lock` never reached the generation workspace.
`pm/runtime.py::_inputs()` hashes `<workspace>/pm/{pyproject.toml,uv.lock}`
to key the PM runtime, so every `hermes pm` command run by the managed
environment's `hermes` died at preflight:
FileNotFoundError: .../workspace/pm/uv.lock
Drop `uv.lock` from the exclusion set. The root lock is unaffected: the
root pass copies only the explicit `files` set (never `uv.lock`), and
`lock_and_sync` seeds or resolves the root lock itself.
