v0.2.0 — Typed vocabularies

Backfilled release note. Originally tagged 2026-06-15; the publish date above is when
this GitHub release entry was created.

Added

• Typed vocabularies: optional, opt-in-beyond-core validation of typed values (single-key
  objects whose key starts with #, e.g. {#utc ...}) against the official vocabularies —
  core, time, network, math, spatial, color, and geo — plus user-registered custom
  vocabularies. New Ron::validate(), and vocabularies / registry options on
  Ron::fromJson, Ron::canonicalRon, and Ron::canonicalHash. The core vocabulary is
  validated by default; pass vocabularies: [] to disable. Validation preserves the value
  model, so typed values round-trip losslessly; Ron::toJson is not validated.
• Mbolli\Ron\Vocabulary\VocabularyRegistry (official(), register(), replace()) for
  declaring custom, reverse-DNS-namespaced vocabularies. A validator returns true/false
  to accept/reject, any other value to transform the payload, or replace($v) to set a
  literal (e.g. boolean) payload.

Changed

• A single #-prefixed key now renders in collapsed typed form ({#tag payload}), with the
  wrapper transparent to indentation and multi-key payloads allowed to inline, matching the
  updated RON spec and ron-go. This changes the rendered RON for documents containing
  single-key #-objects.
