feat: add Fern-generated Python SDK alongside TypeScript

[bhaveshpatel640]

Summary

Add Fern-generated Python SDK (packages/trueforge-python-sdk) next to the TypeScript SDK, and wire CI to regenerate/commit it

Closes AGE-2005

Changes

• Fern python-sdk group (local-file-system) + pnpm sdk:generate / Generate SDK workflow
• Bootstrap pyproject.toml (0.1.0-rc.1) + .fernignore

How was this tested?

• fern generate --group python-sdk locally; optional_auth / version stamp checked
• Workflow path review (no full CI run in this session)

Checklist

• I have read the contributing guidelines
• pnpm build, pnpm test, pnpm typecheck, pnpm lint:ci, and pnpm format:check pass locally
• Tests added/updated where it makes sense
• No hand-edits to generated code (packages/trueforge-sdk, packages/trueforge-python-sdk, .github/fern/openapi/openapi.json, docs/openapi.json) — fork PRs must commit pnpm sdk:generate output (CI cannot push to forks)
• Docs / .env.example updated if configuration or behavior changed

Note

Medium Risk
Adds a large generated surface and changes the SDK automation path; runtime server behavior is unchanged, but CI misconfiguration could drift OpenAPI or SDK commits.

Overview
Introduces a Fern-generated Python API client at python/trueforge_sdk (sync/async TrueForge, streaming, optional auth), generated from the same OpenAPI spec as the TypeScript SDK.

CI and tooling now treat both outputs as one pipeline: Fern python-sdk group in generators.yml, Generate SDK workflow commits python/trueforge_sdk with OpenAPI/TS artifacts (Python excluded from Changesets for now), and contributor docs/checklists forbid hand-editing either SDK tree. .prettierignore skips the Python package.

This PR also includes the initial committed generator output (plus a patch changeset for @truefoundry/trueforge-sdk OpenAPI regen) and minor readme copy from “TypeScript client” to “API client.”
