refactor(cmdline): trim the command-line seams to existing interfaces

The web runtime creates its dev-mode client-hmr row in the root tree
after Loader settlement with plain loader.create, deleting the vendored
Entry.enableRuntime state machine and dsh-cmdline's enableRow export.
Include declares the existing EntryGroup.key tree-carrier marker instead
of the EntryConfigResolver protocol (its own path stays literal; nothing
used a dynamic path). The launcher recognizes no app row: SIGTERM exits
0 on every surface, every boot watches its user patch layers, and the
headless runner exits through ctx.appExit, deleting ctx.headlessIo. Also
restores the vendor README rescope entry to the position the
rescope-vendor exact-edit anchor requires, fixing the master hygiene
regression.
