ruby_llm-ag_ui v0.4.0

[0.4.0] - 2026-10-21

Added

• A proposed public application and custom-store contract, with orchestration
  internals excluded from generated API documentation.
• Explicit RubyLLM 2.1.0 and 2.1.1 CI matrices, and a shared intercepted/live
  OpenRouter harness for text, approval, result association, and reconnect.
• Client-state assertions for one original tool call and one associated result.

Changed

• Remove the unused allow_client_history configuration and diagnostic key.
  Client messages remain untrusted data under host-controlled history policy.
• Reject unsupported protocol_version configuration instead of accepting a
  setting that cannot change the producer's fixed 1.0 output.

Fixed

• Expose the returned reconnect outcome through Run#record, without executing
  the chat again. Verify real RubyLLM denial and installed result association.
• Resume real RubyLLM approval without repeating the original tool-call start
  and arguments. Its result keeps the original call id; new calls still stream.
• Isolate and freeze nested input, identity, interrupt, and JSON record values.
  Editing caller-owned data cannot mutate memory-store indexes or bypass a
  record revision; editing published values raises FrozenError.
