Note

Low Risk
This PR only updates version metadata and the changelog; functional risk sits in the already-merged 2.39.0 features (new RL SDK, deployment/OIDC CLI paths).

Overview
Release 2.39.0 — bumps the published package version from 2.38.0 to 2.39.0 in pyproject.toml, src/together/_version.py, and .release-please-manifest.json, and adds the 2.39.0 section to CHANGELOG.md.

That release bundles previously merged work: first public Reinforcement Learning SDK, CLI/API exposure for deployment concurrency limits and deployment model mounts, structured --debug CLI output, DCI volume creation from S3 via OIDC, plus CLI fixes for list-revisions on models and Jig model mounts internals.
