fix(main): green the post-merge CI (buf lint RPC naming + 100% coverage)

- buf RPC_REQUEST_RESPONSE naming: CloseDFlashSession{Request,Response} ->
  DFlashProposerServiceCloseSession{Request,Response} (buf-approved service-
  prefixed name; avoids the runtime.proto CloseSessionRequest collision).
  Regenerated Python + TS stubs.
- coverage 99->100%: pragma the unreachable defensive guard in
  fused_decode.py (L=min(block,remaining) caps commit at remaining).
