Chatify v0.3.0 — Reactions and Reliability Improvements

Highlights

• Added message reactions with server-side aggregation and client-side rendering.
• Introduced msg_id in message events for safer reaction targeting and replay correlation.
• Added reaction_sync protocol event for reconnect/bootstrap hydration.
• Added client commands for reaction workflows:
  • /react
  • /recent
  • /sync

Improvements

• Hardened server-side validation for reaction payload fields: msg_id and emoji.
• Optimized reaction synchronization by querying reaction events directly.
• Improved client deduplication logic for message IDs and reaction events to prevent double counting.

Test Coverage

• Added contract tests for reaction broadcast and synchronization aggregation flow.
• Added contract tests for invalid reaction payload rejection.
