feat(routes): add _wire.py — registers shared symbols and includes all routers

Called via `import routes._wire` at the bottom of lab_api.py (after all
symbols are defined). Registers every shared object into routes.shared
and mounts all five APIRouters onto the FastAPI app.

Batch 6/6 — final wiring step.

+routes/_wire.py
+===============
+Wires the routes package into lab_api.py.
+
+This module is imported ONCE at the bottom of lab_api.py after all
+symbols (CFG, app, helper functions, endpoint functions) are defined.
+
+It does two things:
+  1. Calls routes.shared._register_shared() so every router can access
+     shared state via routes.shared.get().
+  2. Calls app.include_router() for every APIRouter defined in the
+     routes/ package.
+
+Keeping wiring here means lab_api.py only needs one new line:
+
+    import routes._wire  # noqa — side-effect import
