Bumps google.golang.org/grpc from 1.80.0 to 1.81.0.

Release notes

Sourced from google.golang.org/grpc's releases.

Release 1.81.0

Behavior Changes

  • balancer/rls: Switch gauge metrics to asynchronous emission (once per collection cycle) to reduce telemetry noise and align with other gRPC language implementations. (#8808)

Dependencies

  • Minimum supported Go version is now 1.25. (#8969)

Bug Fixes

  • xds: Use the leaf cluster's security config for the TLS handshake instead of the aggregate cluster's config. (#8956)
  • transport: Send a RST_STREAM when receiving an END_STREAM when the stream is not already half-closed. (#8832)
  • xds: Fix ADS resource name validation to prevent a panic. (#8970)

New Features

  • grpc/stats: Add support for custom labels in per-call metrics (gRFC A108). (#9008)
  • xds: Add support for Server Name Indication (SNI) and SAN validation (gRFC A101). Disabled by default. To enable, set GRPC_EXPERIMENTAL_XDS_SNI=true environment variable. (#9016)
  • xds: Add support to control which fields get propagated from ORCA backend metric reports to LRS load reports (gRFC A85). Disabled by default. To enable, set GRPC_EXPERIMENTAL_XDS_ORCA_LRS_PROPAGATION=true. (#9005)
  • xds: Add metrics to track xDS client connectivity and cached resource state (gRFC A78). (#8807)
  • stats/otel: Enhance grpc.subchannel.disconnections metric by adding disconnection reason to the grpc.disconnect_error label (gRFC A94). This provides granular insights into why subchannels are closing. (#8973)
  • mem: Add mem.Buffer.Slice() API to slice the buffer like a slice. (#8977)

Performance Improvements

  • alts: Pool read buffers to lower memory utilization when sockets are unreadable. (#8964)
  • transport: Pool HTTP/2 framer read buffers to reduce idle memory consumption. Currently limited to Linux for ALTS and non-encrypted transports (TCP, Unix). To disable, set GRPC_GO_EXPERIMENTAL_HTTP_FRAMER_READ_BUFFER_POOLING=false and report any issues. (#9032)

…6.2, regen protos (#77)

- google.golang.org/grpc v1.80.0 → v1.81.0
- google.golang.org/grpc/cmd/protoc-gen-go-grpc v1.5.1 → v1.6.2
- regenerated proto/*.pb.go, proto/*.pb.gw.go, proto/*_grpc.pb.go,
  statik bundle (via `make generate`)

Regen drift is all tooling-cosmetic / harmless:

- pb.go: protoc-gen-go v1.36.4 → v1.36.11 swapped the file-descriptor
  literal from a byte slice (string([]byte{0x...})) to an escaped
  string concat (const "" + "\n" + ...). Same bytes, same wire format.

- pb.gw.go: handlers now `io.Copy(io.Discard, req.Body)` after
  forwarding — grpc-gateway v2.27 "Discard unused body" feature.
  Frees the connection for HTTP/1.1 keep-alive reuse. Already shipped
  in the runtime via T4b; the regen here just brings the generated
  code into sync.

- _grpc.pb.go: UnimplementedFooServer stubs swapped
  status.Errorf(codes.Unimplemented, "...") → status.Error(...) — a
  micro-opt since the format string had no directives. We don't hit
  those stubs anyway since both MilpacsService and TicketsService
  implement every method.

Smoked locally against a fresh XF DB mirror: all 11 baseline
endpoints + 4 connected-account lookups return 200; canonical-jq
content matches the gw snapshot byte-for-byte except for /awol
(grew by one user due to time-sensitive cutoff). OpenAPI page at
/ still serves.

Supersedes #63 and absorbs #61 (whose grpc-only bump is subsumed
by the protoc-gen-go-grpc dependency).

Looks like google.golang.org/grpc is up-to-date now, so this is no longer needed.
