## 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.

> - Require `python ^3.10` in `pyproject.toml` and `.tool-versions`;
update `poetry.lock` metadata and deps to remove 3.9-only
packages/markers

<!-- /CURSOR_SUMMARY -->
- 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)
<!-- CURSOR_SUMMARY -->
> [!NOTE]
> Adds beta MCP support to JS/Python SDKs with template auto-selection,
config POST, MCP URL helpers, and codegen for MCP types/schemas.
>
> - **SDKs (Beta MCP support)**:
> - **JS SDK**:
> - Add `McpServer` types and export; extend `Sandbox.betaCreate` with
`mcp` option that auto-selects `mcp-gateway-v0`, configures MCP via POST
`/config` on port `50005` with retries, and expose `betaGetMcpUrl()`.
> - Add `wait(ms)` util; generate MCP types from `spec/mcp-server.json`;
new `generate:mcp` script and dev dep `json-schema-to-typescript`.
> - **Python SDK**:
> - Generate and export `McpServer` (TypedDict); extend sync/async
`beta_create` with `mcp` option, auto-select default MCP template, POST
MCP config with retries, and add `beta_get_mcp_url()`; define `mcp_port`
and `default_mcp_template`.
> - Makefile: add `generate-mcp` target; include
`datamodel-code-generator` in tooling; update lockfile/pyproject deps.
> - **Tooling**:
> - Add `spec/mcp-server.json` schema; update codegen Dockerfile to
install `datamodel-code-generator`.

**Changelog**
- Adds `files.getInfo`, `files.get_info` methods to the SDKs.
- Adds tests for the new methods
- Adds documentation for the above.
**Examples**
JavaScript
```js
import { Sandbox } from '@e2b/code-interpreter'
const sandbox = await Sandbox.create()
// Create a new file
await sandbox.files.write('test_file.txt', 'Hello, world!')
// Get information about the file
const info = await sandbox.files.getInfo('test_file.txt')
console.log(info)
// {
// name: 'test_file.txt',
// type: 'file',
// path: '/home/user/test_file.txt'
// }
```
Python
```py
from e2b_code_interpreter import Sandbox
sandbox = Sandbox()
# Create a new file
sandbox.files.write('test_file', 'Hello, world!')
# Get information about the file
info = sandbox.files.get_info('test_file')
print(info)
# EntryInfo(name='test_file.txt', type=<FileType.FILE: 'file'>, path='/home/user/test_file.txt')
```

# Description
Fixes an issue in generating files in Docker. There has been an
incompatibility of `buf` (version `29.5`) and `protoc-gen-es` (version
`2.2.2`).
I updated `protoc-gen-es@` to `2.6.2`
Also refactored the code a little so it's easier to read
Added a CI pipeline job to check all files are properly generated
