fix(python): correct PermissionHandler.approve_all type annotations

[giulio-leone]

Summary

Fixes #612

PermissionHandler.approve_all used Any parameter types and returned a plain dict, conflicting with the _PermissionHandlerFn signature:

_PermissionHandlerFn = Callable[
    [PermissionRequest, dict[str, str]],
    PermissionRequestResult | Awaitable[PermissionRequestResult],
]

Changes

• Replace parameter types: Any → PermissionRequest, dict[str, str]
• Replace return type: dict → PermissionRequestResult
• Use PermissionRequestResult() constructor instead of dict literal

Before

def approve_all(request: Any, invocation: Any) -> dict:
    return {"kind": "approved"}

After

def approve_all(
    request: PermissionRequest, invocation: dict[str, str]
) -> PermissionRequestResult:
    return PermissionRequestResult(kind="approved")

Tests

• 15 unit tests passed
• ruff check clean
• 2 consecutive review runs with 0 errors

Pull request overview

Updates the Python SDK’s built-in PermissionHandler.approve_all helper to have type annotations consistent with the _PermissionHandlerFn callback signature expected by SessionConfig.on_permission_request, resolving the type-checker mismatch reported in #612.

Changes:

• Tighten approve_all parameter types from Any to PermissionRequest and dict[str, str].
• Update approve_all return type from dict to PermissionRequestResult.
• Construct the result using PermissionRequestResult(kind="approved") rather than a plain dict literal.
