chore(sync): mirror backend .py + Dockerfile to Space (hf-sync-backend)

Automated backend sync from szl-holdings/a11oy main via hf-sync-backend.
Updated (differed from the Space): Dockerfile, routers/__init__.py, routers/frontier_reads.py, routers/lambda_bounty.py, routers/research_3d.py, serve.py
Deleted (gone from the repo + Dockerfile COPY set): (none)

Keeps the Space-built backend (serve.py + the Dockerfile-COPY'd .py
modules) identical to GitHub main so the Space never rebuilds from a
stale backend, new endpoints don't 404 there, and orphaned modules
removed from the repo don't linger in the Space tree.

+"""a11oy serve.py route-group package (Wave-K Dev4 — refactor-only decomposition).
+
+BACKGROUND
+----------
+serve.py is a ~11.7k-line monolith. This package is the FIRST bounded slice of a
+SAFE, CI-verified decomposition: a small number of cohesive route groups are moved
+out of serve.py into focused modules here, each exposing a single
+
+    def register(app) -> dict
+
+entry point. serve.py imports the package and calls each `register(app)` at the
+SAME lexical position the routes used to occupy — i.e. BEFORE the SPA
+`/{full_path:path}` catch-all — via the established guarded try/except pattern, so:
+
+  * every path is identical,
+  * every method is identical,
+  * the order relative to the catch-all is identical,
+  * a missing/broken group can NEVER take down the SPA (guarded), and
+  * the register() functions are IMPORTED + CALLED (register-invocation-guard clean).
+
+This is REFACTOR-ONLY. No endpoint behavior changes. Parity is proven by
+tools_serve_split/capture_routes.py (before/after route-table fingerprint) plus the
+Wave-J frontier contract suite (tests/test_frontier_endpoints.py) and TestClient.
+
+The package top-level name is `routers` (not szl_*/a11oy_*), so it is intentionally
+OUTSIDE the guarded-import-liveness first-party scan — and the files exist anyway.
