Switches the build tooling for `packages/js-sdk` and `packages/cli` from
`tsup` (esbuild) to `tsdown` (rolldown), replacing each `tsup.config.js`
with a `tsdown.config.ts` and updating the `build`/`dev` scripts and
devDependencies. The published artifact layout is intentionally
unchanged — the SDK still ships `dist/index.js` (CJS), `dist/index.mjs`
(ESM) and `dist/index.d.ts`/`.d.mts`, and the CLI still ships an
executable `dist/index.js` plus `dist/templates` — kept identical via
`fixedExtension: false`. CLI dependency bundling is preserved by mapping
the old `noExternal` to tsdown's `deps.alwaysBundle` (still excluding
the ESM-only, dynamically-imported `inquirer`), and template copying
moves from an `onSuccess` shell step to tsdown's `copy` option.
Also aligns Node versions: `engines.node` for both packages is set to
`20 || >=22`, the CLI build targets `node20`, and the pinned `nodejs` in
`.tool-versions` is bumped to `22.11.0`. The large `pnpm-lock.yaml` diff
is expected — it swaps the tsup/esbuild dependency tree for tsdown's
rolldown tree (no lockfile format change).
## Verification
- Both packages build cleanly with output filenames identical to the
previous tsup builds.
- `typecheck`, `lint` (oxlint) and `build` pass for both packages; the
built CLI runs (`--version`).
- Built js-sdk imports correctly in both CJS (`require`) and ESM
(`import`), exposing the default `Sandbox` export and all named exports.

Migrates the Python SDK's packaging and CI from Poetry to
[uv](https://docs.astral.sh/uv/): `pyproject.toml` is converted to PEP
621 metadata using uv's native `uv_build` backend (verified to produce a
byte-equivalent wheel containing both `e2b` and `e2b_connect`),
`poetry.lock` is replaced with `uv.lock`, and the `Makefile`,
`package.json` scripts, `.tool-versions`, `CLAUDE.md`, and all six
GitHub workflows now use `uv` (`astral-sh/setup-uv` + `uv
sync`/`build`/`version`/`publish`). It also drops the now-redundant
explicit sync steps (since `uv run` auto-syncs) and removes the orphaned
`pydoc-markdown` dev dependency, whose only consumer was deleted long
ago — trimming 58 packages from the dev lockfile.
## Usage
```sh
cd packages/python-sdk
uv sync # install deps (replaces `poetry install`)
uv run pytest # run tests
uv build # build the wheel/sdist
make lint # ruff (run via `uv run`)
```
No user-facing SDK change — packaging/tooling only — so no changeset is
included; the published package contents are unchanged.

- Individual tests must complete in less than 5 minutes
- Add a `make test` option that runs tests
- Upgrade poetry to 2.1.1 (the lock file was generated by this version,
so this just matches what we already expect)
This way a version bump in the `.tool-versions` file is automatically
used in tests, linters, releases, and local dev. It also helps make it
clear which version we expect people to use locally.

`wistia/parse-tool-versions@v2.1.1` in `cli_tests.yml`,
`generated_files.yml`, `js_sdk_tests.yml`, `lint.yml`,
`publish_packages.yml`, `python_sdk_tests.yml`, `release.yml`,
