Major release. Driven by a single observable-contract change: WebhookSubscription.equals() and .hashCode() are now identity-based on id, not value-based on every field. The prior value-based equality was a bug — WebhookSubscription is an entity, not a value object — but equals/hashCode are part of the public Java contract that callers depend on for set deduplication, map lookup, and identity caches, so the fix is breaking per strict semver. Bumps: - pom.xml: 5.7.0 -> 6.0.0 - CHANGELOG [Unreleased] -> [6.0.0] - 2026-04-25 Wire-shape baseline regenerated against community SHA 10d44eb4 (post platform v7.4.2 spec corrections). DynamicPolicyInfo entry auto-resolves. Net 39 -> 38. Coordinated v6 alignment release: ships same day as TypeScript v6.0.0, Python v6.7.0, Go v5.7.0. The TS and Java repos needed major bumps; Python and Go ship as minor because their changes are purely additive.

Summary
Major release — driven by a single observable-contract change.
`WebhookSubscription.equals()` and `.hashCode()` are now identity-based on `id`, not value-based on every field. The prior value-based equality was a bug — `WebhookSubscription` is an entity, not a value object — but `equals` / `hashCode` are part of the public Java contract that callers depend on for set deduplication, map lookup, and identity caches, so the fix is breaking per strict semver. See CHANGELOG `[6.0.0]` for the rationale.
The 6-arg constructor is preserved as a source-compat overload for callers building local instances; only `equals` / `hashCode` semantics changed.
Bumps
Wire-shape baseline regen
Pin SHA bumped `bf1ca22a` → `10d44eb4`. `DynamicPolicyInfo` auto-resolves. Net 39 → 38.
Coordinated release
Ships same day as TS v6.0.0 (PolicyInfo rename — the other BREAKING SDK), Python v6.7.0 (additive — minor), Go v5.7.0 (additive — minor). The semver asymmetry is principled.
