python3-autobahn: Upgrade 25.11.1 -> 25.12.2

Upgrade to release 25.12.2:

Build & CI/CD:

- Synchronize CI/CD, FlatBuffers vendoring, and wamp-ai/wamp-cicd
  submodules between autobahn-python and zlmdb
- Switch manylinux container from 2_34 to 2_28 for x86_64 ISA
  compatibility (fixes auditwheel flatc bundling)
- Increase ARM64 build timeout to 60 minutes for QEMU emulation
- Add .github/workflows/README.md documenting CI/CD architecture
- Consolidate download-github-release and download-release-artifacts
  recipes
- Add checksum verification to artifact download workflow

FlatBufers:

- Simplify vendored FlatBuffers - use upstream as-is
- Track vendored FlatBuffers in git (like zlmdb approach)
- Add version() function to vendored FlatBuffers runtime
- Add check_zlmdb_flatbuffers_version_in_sync() for cross-project
  compatibility
- Generate .bfbs files for WAMP schemas during wheel build

Other:

- Rename install-flatc to install-flatc-system with prominent warning
- Remove legacy readthedocs.yml to activate .readthedocs.yaml
- Remove dev-latest optional dependency (PyPI rejects direct URLs)
