feat: Python telemetry client SDK v0.1.0

Standalone Python package (mosaicstack-telemetry) for reporting
task-completion telemetry and querying predictions from the Mosaic
Stack Telemetry server.

- Sync/async TelemetryClient with context manager support
- Thread-safe EventQueue with bounded deque
- BatchSubmitter with httpx, exponential backoff, Retry-After
- PredictionCache with TTL
- EventBuilder convenience class
- All types standalone (no server dependency)
- 55 tests, 90% coverage, mypy strict clean
