v2.14.2

This is a maintenance release:

Enhancements

• Add a new Avro package "avrov3" which uses confluent-avro-go, Confluent's
  fork of the now-archived hamba/avro library. avrov3 picks up the upstream
  little-endian decoding fix for floats and doubles (per the Avro spec) and
  hamba bug fixes accumulated since v2.24.1, including correct unwrapping
  of union-typed fields when decoding into map[string]interface{}. The
  existing "avrov2" package remains supported on hamba/avro for backwards
  compatibility; new code should prefer avrov3.
• Note: adopting avrov3 bumps this module's go directive from 1.24.3 to
  1.25.0, since confluent-avro-go/v2 v2.32.0 requires Go 1.25.0+. Users on
  Go 1.24.x with GOTOOLCHAIN=auto (the default since Go 1.21) will fetch a
  1.25 toolchain transparently; users with GOTOOLCHAIN=local must upgrade
  to Go 1.25.0 or later.
• Note: confluent-avro-go/v2 v2.32.0 transitively raises the minimum
  versions of several dependencies: github.com/go-viper/mapstructure/v2
  (v2.0.0 → v2.5.0), github.com/klauspost/compress (v1.17.9 → v1.18.5),
  github.com/stretchr/testify (v1.9.0 → v1.11.1), and golang.org/x/sync
  (v0.8.0 → v0.20.0).
• Removed integration test dependencies from the kafka module (#1555).
• Bump golang.org/x/net to v0.55.0 to fix: GO-2026-5026 in idna, GO-2026-4918 in HTTP/2 transport (#1555).

• Handle anyOf/allOf in JSON transforms #1539
