PR #3: Session Telemetry Integration

Description

Integrates session identifiers across all telemetry instrumentation modules,
using the infrastructure established in PR #2.

This PR adds session IDs to:

Instrumentation Coverage

• ✅ ANR (Application Not Responding) - Session context for app freezes
• ✅ Crash reporting - Link crashes to user sessions
• ✅ View clicks - Track user interactions per session
• ✅ Compose clicks - Session context for Jetpack Compose UI
• ✅ Network changes - Correlate connectivity with sessions
• ✅ WebSocket events - Session tracking for real-time connections
• ✅ Slow rendering / jank - Performance issues per session
• ✅ App startup events - Session initialization tracking

Integration Points

• SessionIdSpanAppender - Automatically adds session IDs to all spans
• SessionIdLogRecordAppender - Automatically adds session IDs to all log records
• Factory Pattern - SessionProviderFactory and SessionManagerFactory
• Configuration DSL - Easy session configuration in OpenTelemetryRumInitializer

Example Usage

OpenTelemetryRumInitializer.initialize(context) {
    session {
        // Session expires after 15 minutes in background (default)
        backgroundInactivityTimeout = 15.minutes

        // Session expires after 4 hours regardless of activity (default)
        maxLifetime = 4.hours
    }
}

Result: All telemetry data now includes session context (session.id and session.previous_id) for comprehensive session-based observability.
