fix(runtime): satisfy ty in runtime tests

[Subhajitdas99]

Summary

• Problem: Updated runtime tests fail ty due to stale type: ignore comments and nullable await_args access in mocked async calls. The runtime provider code also imports the optional boxd dependency, which ty could not resolve in the default test environment.
• Why it matters: These typing issues block unrelated PRs in CI even when their own changes are clean.
• What changed: Removed unused type: ignore directives, added explicit non-None assertions before accessing await_args.args / await_args.kwargs, and added minimal local boxd stub files so ty can resolve the optional runtime dependency during static analysis.
• What did NOT change: No production runtime behavior changes, no CLI behavior changes, and no test logic changes beyond type-safety guards and type-checking stubs.

User-Visible / Behavior Changes

None.

Security Impact (required)

• New permissions/capabilities? (Yes/No) No
• Secrets/credentials handling changed? (Yes/No) No
• New/changed network calls? (Yes/No) No
• Database schema/migration changes? (Yes/No) No
• Authentication/authorization changes? (Yes/No) No
• If any Yes, explain risk + mitigation: None

Verification

Environment

• OS: Windows 11
• Python version: 3.12.9
• Storage backend: Not applicable
• Scheduler backend: Not applicable

Steps to Test

1. Run uv run pre-commit run --all-files
2. Confirm ty no longer reports unused type: ignore comments in the runtime test base file
3. Confirm ty no longer reports nullable await_args access or unresolved boxd imports in the runtime provider/test paths

Expected Behavior

• Pre-commit no longer fails on these runtime typing issues.
• Test behavior remains unchanged.

Actual Behavior

• Removed the stale suppressions, added explicit non-None guards, and provided minimal local boxd stubs for static analysis.
• Pre-commit passed locally on commit.

Evidence (attach at least one)

• Failing test before + passing after
• Test output / logs
• Screenshot / recording
• Performance metrics (if relevant)

Human Verification (required)

• Verified scenarios: Verified the affected runtime tests now guard nullable await_args access and no longer rely on unused type: ignore comments. Verified ty can resolve the optional boxd import path via local stubs.
• Edge cases checked: Checked both log-streaming assertions and shell exec assertions where mocked await_args is read. Checked that the minimal stub surface covers the imported runtime symbols used by static analysis.
• What you did NOT verify: Did not change or re-verify production runtime behavior against a live boxd installation, since this PR is focused on static-analysis/test-path cleanup.

Compatibility / Migration

• Backward compatible? (Yes/No) Yes
• Config/env changes? (Yes/No) No
• Database migration needed? (Yes/No) No
• If yes, exact upgrade steps: None

Failure Recovery (if this breaks)

• How to disable/revert this change quickly: Revert this PR.
• Files/config to restore:
  • tests/unit/runtime/test_base.py
  • tests/unit/runtime/test_boxd_provider.py
  • tests/unit/runtime/test_cli_shell_logs.py
  • boxd/__init__.pyi
  • boxd/aio.pyi
  • boxd/errors.pyi
• Known bad symptoms reviewers should watch for: Unexpected test assertion failures if a mocked async call stops being awaited, or future boxd imports require additional stubbed symbols for static analysis.

Risks and Mitigations

• Risk: The local boxd stubs may need expansion if additional optional SDK symbols are imported later.
  • Mitigation: Kept the stubs intentionally minimal and limited to the symbols currently referenced by ty in the runtime provider/tests.

Checklist

• Tests pass (uv run pytest)
• Pre-commit hooks pass (uv run pre-commit run --all-files)
• Documentation updated (if needed)
• Security impact assessed
• Human verification completed
• Backward compatibility considered

📝 Walkthrough

Walkthrough

This PR introduces type stubs for box configuration, async compute management, and exception types, along with test refactoring to add null-safety assertions and remove type-ignore comments. Five new/updated files define configuration contracts and improve test reliability.

Changes

Box Configuration and Async Compute APIs

Layer / File(s)	Summary
Configuration Data Contracts boxd/__init__.pyi	ProxyEntry, NetworkConfig, LifecycleConfig, and BoxConfig form a composition hierarchy defining box resource configuration, networking, and lifecycle management.
Async Context Manager Interface boxd/aio.pyi	Compute class implements async context-manager protocol with __aenter__ returning Compute and __aexit__ handling cleanup.
Exception Definitions boxd/errors.pyi	NotFoundError exception type added as a public exception.
Test Code Cleanup and Simplification tests/unit/runtime/test_base.py	Removes type: ignore comments from FakeProvider and simplifies method bodies to ellipsis form; RuntimeProvider instantiation assertion simplified.
Test Assertion Safeguards tests/unit/runtime/test_boxd_provider.py, tests/unit/runtime/test_cli_shell_logs.py	Four test methods add explicit null checks for fake_box.exec.await_args before accessing command arguments in log-streaming and shell tests.

Poem

🐰 Behold, a box of types so neat,
With proxies, lifecycle, and compute so sweet,
The tests now guard their null checks tight,
Type stubs defined, the contracts bright!
No more ignores—just clean code right. 🎉
