[1/7] Telemetry Foundation: Types, Config, and Exception Classifier (#…

…324)

* Add telemetry foundation: types, config, and exception classifier

This is part 1 of 7 in the telemetry implementation stack.

Core Components:
- Telemetry type definitions for events, metrics, and configuration
- Exception classifier for terminal vs retryable error classification
- Client context telemetry configuration fields

Type Definitions:
- TelemetryEvent: Runtime events emitted by driver
- TelemetryMetric: Aggregated data exported to Databricks
- DriverConfiguration: Driver metadata and feature flags
- StatementMetrics: Per-statement aggregation data
- TelemetryConfiguration: Config for telemetry features

Exception Classification:
- Terminal errors (401, 403, 404, 400, AuthenticationError) - flush immediately
- Retryable errors (429, 500, 502, 503, 504, timeouts) - buffer until complete
- Smart flushing optimizes export efficiency

Testing:
- 51 comprehensive unit tests for ExceptionClassifier
- 100% coverage of edge cases and error types

This provides the foundation for subsequent telemetry layers.
