Update Ruff and ty tooling

[xeophon]

Overview

Updates the repository tooling to Ruff 0.16.0 and ty 0.0.63, with hooks using the locked project environment.

Details

• Pins both tools in the development dependency group and refreshes the lockfile.
• Adds bounded package-specific freshness cutoffs for the explicitly selected releases.
• Runs the Ruff and ty hooks with uv run --locked so local hooks use the committed versions.
• Adds rule-scoped ty suppressions for pre-existing diagnostics in the legacy code checked by the newer ty release.

This PR is stacked on #2147 to keep the tooling upgrade separate from the Ruff cleanup.

Note

Low Risk
Tooling and type-check suppressions only; no production logic changes. Main risk is CI/pre-commit failing if Ruff 0.16 or ty 0.0.63 report new issues beyond the added ignores.

Overview
Upgrades Ruff to 0.16.0 and ty to 0.0.63, with dev dependency floors, a refreshed uv.lock, and tool.uv.exclude-newer-package cutoffs for those two tools.

CI pins Ruff 0.16.0 in the style workflow. Pre-commit runs Ruff and ty via uv run --locked so hooks match the lockfile.

Across verifiers/, adds ty:ignore[...] (alongside existing type ignores) for diagnostics surfaced by the newer ty release—clients, envs, rubrics, utils, and related paths—without changing runtime behavior.

Note

Update Ruff and ty tooling to fix mutable default and type annotation issues across the codebase

• Bumps ruff to >=0.16.0 and ty to >=0.0.63 in pyproject.toml and updates CI in style.yml to match.
• Adds # ruff: noqa file-level directives to ~100 files where existing code patterns cannot cleanly satisfy the stricter rules.
• Fixes shared mutable default bugs in multiple Pydantic models (TaskConfig, RetryConfig, NetworkPolicyConfig, RubricJudgeConfig, EnvServerConfig, etc.) by replacing bare list/dict literals with Field(default_factory=...).
• Changes several ValueError raises to TypeError in type-guard and validation contexts (agent.py, harness.py, egress.py, agentic_judge/env.py, etc.) to align with Python conventions.
• Replaces typing.Callable/typing.Iterator imports with collections.abc equivalents and updates asyncio.TimeoutError catches to TimeoutError in EnvClient.
• Risk: EnvClient._request and EnvClient.ping_server now catch TimeoutError instead of asyncio.TimeoutError; since asyncio.wait_for raises asyncio.TimeoutError (a subclass of TimeoutError), this is functionally equivalent, but callers relying on asyncio.TimeoutError type specifically may be affected.

Approvability

Verdict: Approved

Mechanical tooling upgrade updating Ruff linter and ty type checker versions. Changes are formatting adjustments, import reordering, lint/type ignore comments, and minor Pydantic mutable default fixes. No significant runtime behavior changes.
