## Summary
- Update the vendored
[json-parser](https://github.com/json-parser/json-parser) implementation
in `srs_protocol_json.cpp` from the verified upstream revisions for
`json.h` and `json.c`.
- Record the upstream repository, per-file revisions, dates, and
synchronization date so future AI-assisted maintenance can determine
whether another update is needed.
- Scope Clang's deprecated-declaration warning suppression to the
vendored block, preserving the upstream parser code while eliminating
the macOS `sprintf` warnings.
- Improve the local AI setup documentation by clarifying the related
Oryx and Dev Docker repositories and reorganizing the agent guidance.
