Patch Changes

• 1849a5f: fix(ai): preserve hydrated partial static tool input across stream resumptions
• 5381c08: fix(ai): keep idle UI message streams open with optional SSE heartbeats
• 06e8d1c: Encode chat IDs in default stream reconnection URLs so slashes, query delimiters, and fragments stay within the ID. Reject standalone . and .. IDs before fetching. Custom URLs returned by prepareReconnectToStreamRequest remain unchanged.
• 58d303f: Preserve prototype-named tools, providers, and provider metadata as own properties without changing lookup object prototypes. Prevent inherited names from resolving as registered providers or causing image metadata aggregation to fail.
• 430ae0a: Prevent automatic chat resumption when completed tool output is followed by terminal text without a completed stream state, while preserving resumption after completed model text.
• Updated dependencies [07e394b]
• Updated dependencies [b6cf409]
  • @ai-sdk/gateway@2.0.161
