Release/v1.62.0 (#4400)

traces/exporters/gcp v0.1.0

- Feature: keyless trace export to Google Cloud. TRACE_EXPORTER=gcp sends spans to Google Cloud's Telemetry (OTLP) API using Application Default Credentials: no key file and no Collector sidecar, and tokens refresh on their own (#4207)
- Grant roles/telemetry.tracesWriter (least privilege); sets the gcp.project_id resource attribute from the ambient credentials, falling back to GOOGLE_CLOUD_PROJECT
- Requires gofr.dev v1.62.0, the first release with the trace exporter registry (#4408, #4409)

metrics/exporters/gcp v0.2.1

- Fix: each export is split into requests of at most 200 points, the Telemetry API limit
- before, a long-running process eventually exceeded it and every later collection was lost (#4267)
- dependency updates.

datasource/surrealdb v0.3.6

- Lint cleanups (no behavior change)
- dependency updates
- more test coverage.

datasource/solr v0.1.4

- Dependency updates
- more test coverage.

datasource/scylladb v0.1.5

- Fix: QueryWithCtx now closes the gocql iterator and returns the query error, instead of reporting a failed query as an empty result (#4252)
- batch type is mapped to gocql.BatchType explicitly (same values)
- reflect.Pointer replaces reflect.Ptr
- dependency updates.

datasource/pubsub/sqs v0.1.4

- Named constants for repeated literals (no behavior change)
- dependency updates.

datasource/pubsub/nats v0.2.5

- Named constants for repeated literals (no behavior change)
- dependency updates
- more test coverage.

datasource/pubsub/eventhub v0.6.0

- Feature: Health() now probes the broker (GetEventHubProperties) and reports the real partition count, instead of only the local connection state (#3649)
- Fix: at most one health probe runs at a time, so a broker that accepts a connection but never answers no longer leaks a goroutine per poll (#4156)
- dependency updates.

datasource/oracle v0.1.5

- Fix: Exec and Select take their start time before the driver call, so recorded durations measure the real call instead of ~0 (#4298)
- reflect.Pointer replaces the deprecated reflect.Ptr
- dependency updates.
