Note

Medium Risk
Primarily a release/version bump, but it publishes breaking API changes (move to unified Runner.run()/RunnerResult and removal of invoke_* methods), which can break downstream integrations.

Overview
Cuts a new release across the core SDK and provider packages: launchdarkly-server-sdk-ai to 0.19.0, LangChain provider to 0.6.0, and OpenAI provider to 0.5.0, updating the release manifest and package metadata accordingly.

Changelogs document the shipped breaking API surface changes (notably removing invoke_model()/invoke_structured_model() in favor of run(...) and standardizing returns on RunnerResult) plus accompanying feature/fix entries; the core package version constants/docs (__version__, PROVENANCE.md) are updated to match.
