RustDesk protobuf schemas — vendored from rustdesk/hbb_common

Source:   https://github.com/rustdesk/hbb_common
Path:     protos/message.proto, protos/rendezvous.proto
Ref:      master
Fetched:  2026-07-22 (via raw.githubusercontent.com/rustdesk/hbb_common/master/...)
Package:  hbb  (both files; no cross-imports)

NOTE ON PINNING
  The sandbox that vendored these could reach raw.githubusercontent.com but not
  the GitHub REST API or the git smart-HTTP endpoint, so an exact commit SHA
  could not be recorded here. Before shipping, re-vendor from a pinned tag/SHA
  (spec §4 Phase 4: "Pin vendored protos to an exact hbb_common ref; scripted
  re-vendor + diff on upstream releases") and replace `Ref: master` above with
  the exact SHA.

REGENERATE the TypeScript types after any re-vendor:
  npm run gen        # runs protoc / ts-proto per buf.gen.yaml settings
  (see webclient/README.md → "Regenerating protobuf types")
