feat: route telemetry directly to Azure Application Insights#37
Conversation
Replace altimate-backend ingest with direct App Insights ingestion. Instrumentation key is baked in so all npm installs report automatically with no user configuration. `APPLICATIONINSIGHTS_CONNECTION_STRING` env var overrides the default for dev/testing. Events are mapped to App Insights custom event format: - `customDimensions` — string fields (model_id, provider_id, etc.) - `customMeasurements` — numeric fields (cost, duration_ms, token counts) - `tokens.*` payload is flattened to `tokens_input`, `tokens_output`, etc. - `ai.user.id` tag captures the authenticated user's email
