✨ Update dependencies, enhance NATS consumer configuration, and improve error handling in message processing. Introduce telemetry support with OpenTelemetry for tracing and metrics. Refactor README to include new configuration options and update tests for improved coverage of error scenarios.

 ### Timeouts and Ack Wait
 
 `[timeouts]` is optional, but if you plan to tune JetStream redelivery you should set `timeouts.ack_wait` and/or `[nats.consumer].ack_wait`. When neither is specified the application defaults both values to `30s`, ensuring predictable redelivery timing.

+| `--subject`         | `subscription.topic`   | Change the subscribed subject filter   |
+| `--stream`          | `nats.stream`          | Bind to another JetStream stream       |

+
+#### Replay & Backoff
+
+- `--replay-from seq:12345` replays from a specific JetStream sequence, while `--replay-from time:2024-11-15T08:00:00Z` starts at a timestamp.
+- Configure server-side retry delays with `[nats.consumer].backoff = ["5s", "30s", "2m"]`; each duration becomes the delay before the next delivery attempt.
+- Combine `backoff` with `--ack-wait` to increase acknowledgement windows (e.g., `--ack-wait 2m`).
+
+### Telemetry
+
+- Enable tracing/metrics via `[telemetry] enabled = true` and set `endpoint` to your OTLP/HTTP collector (e.g., `http://otel-collector:4318`).
+- CLI overrides:
+  - `--telemetry-enabled` flips the feature on/off.
+  - `--telemetry-endpoint` and `--telemetry-insecure` adjust the OTLP HTTP endpoint and TLS behavior.
+- When enabled the app emits OpenTelemetry traces (parser/repository/publisher spans) and JetStream metrics (ack pending, deliveries) for dashboards and alerts.

+
+| Status                | Description                                      |

 ## Message Parsing
 
 The system supports parsing of aviation telegram messages in the standard ICAO format. All messages follow a common header structure, followed by a message body that varies by message type.
