Wrap typed change payloads in a conventional event envelope with id, occurred_at, source, and schema_version.
Rename the current wire payload to ChangeV1 and make the event envelope generic for future schema versions.
Remove event source metadata and store occurred_at as an RFC 3339 OffsetDateTime.
Replace time::OffsetDateTime with chrono::DateTime<Utc> for RFC 3339 event timestamps.
Treat duplicate version deletion events as a no-op so temporary event-based handling can safely replay them.
Add watcher config fields for an SQS queue URL and region to support an event-based path.
Use url::Url for the watcher SQS queue URL config so invalid values fail during config loading.
Update Cargo.lock after making docs_rs_watcher depend directly on url.
Remove the redundant schema_version field from the crates.io event envelope and keep versioning in the typed payloads.

Rename the SQS subscriber entrypoints to better reflect the transport, body-handling, and event-processing layers.
Supervise the SQS subscriber separately in mixed mode so SQS failures are logged and restarted without stopping the legacy registry watcher.
Add starter counters and histograms for SQS intake, failures, retries, processing time, event lag, and applied change types, and record them from the subscriber flow.
Add buckets around the one-minute visibility timeout so slow message handlers are easier to spot in metrics.
