fix: inject /v1/doctrine via szl_smoke_fix.py in serve.py + Dockerfile [smoke-fix-pass1]

Backend smoke fix: /api/killinchu/v1/doctrine was missing.
szl_smoke_fix.register(app, "killinchu") injected BEFORE /{full_path:path} catch-all.
Dockerfile updated with COPY szl_smoke_fix.py.
Doctrine v11 LOCKED 749/14/163 UNCHANGED. Kernel c7c0ba17. Λ = Conjecture 1.
