• Tests added/updated where it makes sense
• No hand-edits to generated code (packages/trueforge-sdk, .github/fern/openapi/openapi.json, docs/openapi.json) — fork PRs omit SDK regen; maintainers regenerate after merge
• Docs / .env.example updated if configuration or behavior changed

Note

Medium Risk
Changes release automation and adds a new PyPI publish path; misconfiguration could block releases or publish wrong versions, though npm/chart gates are unchanged and PyPI skips existing versions.

Overview
Adds PyPI publishing for trueforge-sdk on the same Changesets-driven Release workflow as npm, using a new publish-python job (OIDC via pypa/gh-action-pypi-publish, skip-if-already-on-PyPI check, build with python -m build).

Version lockstep: scripts/version.mjs now copies @truefoundry/trueforge-sdk’s version into python/trueforge_sdk/pyproject.toml, regenerates both Fern SDKs, and stages the Python tree; generate-sdk.sh / SDK regen comments reflect that Python tracks TS on Version Packages (no separate Python changeset in bot regen).

Docs: RELEASING.md documents PyPI triggers, mirroring, trusted publishing setup, and troubleshooting.

The diff also bumps OpenAPI/SDK metadata to 0.2.0-rc.7 (OpenAPI) / 0.2.0-rc.4 (Python package literals from regen)—artifact/version alignment from the regen path, not new API surface in this PR.
