engine: bump version to 0.224.0

[sxlijin]

Summary

• Bump the engine and SDK release family from 0.223.0 to 0.224.0 after fix(openai): preserve content-block metadata on openai-responses (GPT-5.6 prompt_cache_breakpoint) #4155 merged.
• Regenerate Cargo and SDK integration-test artifacts at the new version.
• Replace the raw 461-line generated changelog entry with curated engine-facing release notes, including the baml.unstable.string → string.from breaking change and the OpenAI Responses API metadata fix from fix(openai): preserve content-block metadata on openai-responses (GPT-5.6 prompt_cache_breakpoint) #4155.

Impact

Prepares the next full minor engine release across Python, TypeScript, Ruby, Go, Rust, VS Code, Zed, JetBrains, and integration-test version manifests.

Validation

• ✅ TypeScript native build and client generation
• ✅ Python native build and client generation
• ✅ cargo test -p baml-runtime responses_api --lib (4 passed)
• ❌ TypeScript integration tests: 220 passed, 16 failed. Failures include the retired claude-3-haiku-20240307 model, invalid AWS test credentials, and live-provider/test-environment failures; the generated JUnit report is committed.
• ❌ Python integration tests: 304 passed, 4 skipped, 39 failed, 6 errors. Failures include live-provider DNS/model/credential issues plus collector/emit assertions.

Generated with tools/bump-version and completed manually from its build step after bootstrapping the fresh clone's locked dependencies.

Poem

A rabbit hops through version lines,
Where every package neatly shines.
Changelogs bloom, clients align,
Test reports mark the release time.
“0.224.0!” the bunny sings.
