## Summary
- Resolved 43 type diagnostics reported by ty (Astral's Python type
checker)
- Fixed Self type issues on class singletons
- Added explicit type annotations for shadowed attributes
- Replaced None with UNSET for auto-generated API parameters
- Fixed method signature alignment for protocol matching
- Added targeted type: ignore suppressions for pattern-based limitations
All checks pass: ty check, ruff format, ruff check.

---
> [!NOTE]
> **Medium Risk**
> Mostly typing/CI changes, but some adjustments affect sandbox
connect/pause overload dispatch and API response/parameter handling
(`UNSET` vs `None`), which could alter edge-case runtime behavior.
>
> **Overview**
> Fixes Python SDK static typing issues for Astral’s `ty` checker and
wires typechecking into CI.
>
> Adds a new `Typecheck` GitHub Action plus workspace `typecheck`
scripts (TS packages via `tsc`, Python SDK via `make typecheck` running
`ty`), and publishes a patch changeset for `@e2b/python-sdk`.
>
> Across the Python SDK, adjusts type annotations and overloads (e.g.,
`Self`/singleton typing, `connect` overloads, optional
`user`/token/domain handling), tightens API model parsing with
`cast`/`Optional` checks and `UNSET` usage, and adds a few targeted `ty`
ignore comments in tests/protocols to silence checker limitations.
