russell@unturf.com 1e01d09883 feat: per-client Makefile infrastructure for 4-mode testing
Add per-client Makefiles for C, Python, and Go with:
- CLI mode: Tests --help, arg parsing, syntax validation
- Library mode: Unit tests, import verification
- Integration mode: API contract validation (with credentials)
- Functional mode: Real-world scenario tests

C client:
- 22 library tests (SHA-256, HMAC-SHA256, detect_language)
- Full unsandbox.c implementation with examples

Python client (sync + async):
- Delegates to sync/ and async/ subdirectories
- pytest-based test suites with coverage
- Examples for concurrent execution, streaming

Go client:
- Delegates to sync/ and async/ subdirectories
- go test integration with vet and fmt

Also update detect-changes.sh to detect changes in
both root-level un.* files AND clients/ directory.

"""
Fibonacci example for unsandbox Python SDK - Asynchronous Version
Demonstrates concurrent fibonacci calculations using async/await.
Shows how to run multiple concurrent CPU-bound operations.
To run:
export UNSANDBOX_PUBLIC_KEY="your-public-key"
export UNSANDBOX_SECRET_KEY="your-secret-key"
python3 fibonacci_async.py
Expected output:
Starting 3 concurrent fibonacci calculations...
[fib-10] Result: fib(10) = 55
[fib-15] Result: fib(15) = 610
[fib-12] Result: fib(12) = 144
All calculations completed!
