feat(telemetry): complete ollama-stream-telemetry.sh implementation

[aygp-dr]

Current script needs the following improvements:

1. Docker/Proxy Integration:

   • Fix URL handling for host.docker.internal vs localhost
   • Handle proxy authentication if needed
   • Better error messages for proxy connection failures
   • Add proxy status to telemetry output

2. Streaming Output:

   • Ensure proper ndjson handling
   • Handle chunked transfer encoding correctly
   • Add progress indicators for long responses

3. Telemetry Enhancements:

   • Add network latency metrics
   • Calculate tokens/second rate
   • Track connection retries
   • Add timing for proxy vs direct connections

4. Error Handling:

   • Better curl error parsing
   • Retries with exponential backoff
   • Timeout handling
   • Signal handling (CTRL+C)

5. Documentation:

   • Add detailed usage examples
   • Document mitmproxy integration
   • Add configuration guide
   • Document metrics format

6. Testing:

   • Add test cases
   • Mock responses
   • Proxy failure scenarios
   • Various model scenarios

7. CI Integration:

   • Add GitHub action
   • Automated tests
   • Shellcheck integration
   • Version tagging

Context:
The script was created as part of the OpenTelemetry integration effort. It currently supports basic streaming and telemetry but needs hardening for production use.
