Note

Low Risk
Release-only changes (version numbers, manifest, and changelogs) with no functional code modifications beyond __version__ updates.

Overview
Release Please version bump across packages. Updates .release-please-manifest.json, package pyproject.toml versions, and ldai.__version__ for launchdarkly-server-sdk-ai (0.16.1 → 0.17.0), LangChain provider (0.3.2 → 0.4.0), OpenAI provider (0.2.1 → 0.3.0), and publishes launchdarkly-server-sdk-ai-optimization (0.1.0).

Adds corresponding CHANGELOG.md entries and updates PROVENANCE.md with the new SDK version.

Hold off on merging this. I am working to merge in all of the Agent Graph work so that we don't have multiple breaking change versions.

Optimization package version not bumped to 0.1.0

Medium Severity

The optimization package's pyproject.toml is bumped to 0.1.0, but packages/optimization/src/ldai_optimization/__init__.py still has __version__ = "0.0.0". The release-please-config.json lists this __init__.py as an extra-file that should be updated, but it was missed — likely because it lacks the # x-release-please-version marker comment. Anyone checking ldai_optimization.__version__ at runtime will see "0.0.0" instead of "0.1.0".
