feat: add QNX process configuration, schema, docs for TimeSlave reference Integration

[gordon9901]

This PR adds the configuration required to build and run the TimeSlave process on QNX:

• Add QNX JSON configuration for TimeSlave (iface_name, PHC, QNX BPF shim settings)
• Add a representative example configuration showing all supported fields
• Add JSON Schema (Draft 2020-12) plus a Bazel validate_json_schema_test lint rule
• Add Bazel build infrastructure: ITF framework, rules_pkg, rules_oci, score_rules_imagefs, json-schema-validator
• Add QNX setup documentation covering prerequisites, build/run steps, and config usage
• Add QEMU reference integration test verifying binary/config deployment, interface presence, and config loading under QNX

Closes #141
