Replace the WrennClient-centric API with a top-level Capsule class that
mirrors e2b's Sandbox interface, enabling drop-in migration. Key changes:
- Capsule/AsyncCapsule with direct construction (reads WRENN_API_KEY and
WRENN_BASE_URL env vars), namespaced sub-objects (capsule.commands,
capsule.files), dual instance/static lifecycle methods via _DualMethod
descriptor (capsule.kill() and Capsule.kill(id))
- WrennClient simplified to API-key-only endpoints (capsules, snapshots);
JWT-based resources (auth, hosts, teams) removed
- wrenn.code_interpreter submodule with Capsule subclass defaulting to
code-runner-beta template and run_code() support
- Sandbox alias emits FutureWarning instead of DeprecationWarning

Add sandbox filesystem methods (list_dir, mkdir, remove, upload,
download, stream_upload, stream_download) and interactive PTY sessions
(PtySession, AsyncPtySession) with reconnect support per
FILE_TERMINAL.md spec. Refactor error handling into exceptions.py as
shared handle_response(). Replace API-key-only proxy auth with unified
_proxy_headers() supporting both API key and JWT. Fix stream_upload to
build multipart manually instead of relying on httpx files= with
generators. Switch Makefile SPEC_URL from main to dev branch. Regenerate
models from updated OpenAPI spec (adds teams, channels, metrics, PTY
endpoints). Add comprehensive unit and integration tests. Trim AGENTS.md
to verified facts only.
