Bridges the per-bottle `prepare` output to the consolidated registry:
`registration_inputs(plan)` turns a prepared egress plan into the
backend-neutral inputs `Orchestrator.launch_bottle` takes.
- egress_policy(plan): the policy blob = the exact routes YAML the
per-bottle sidecar read from a file; the multi-tenant gateway's
PolicyResolver now fetches it from the registry per request instead.
Same egress_render_routes, so a bottle's allow-list is byte-identical
moving onto the shared gateway.
- RegistrationInputs bundles policy + metadata; metadata carries the human
slug so the shared registry can map a minted bottle id back to a name
(console / supervise display).
Host-side glue (imports bot_bottle.egress) used by the launch path — not
the lean orchestrator control-plane process. Not yet wired into launch
(that's 13c/13d), consistent with the slice-6/10 pattern of landing the
primitive before the cut-over.
Key test: the policy round-trips through load_config back to the same
routes + log level — the resolver-served policy reconstructs the per-bottle
egress config exactly.
pyright 0 errors; pylint 9.83/10; unit suite green (1718 tests; the 13
test_sidecar_init /bin/sleep errors are pre-existing NixOS-local noise).
