test: run app-server integration tests with Wine exec

[anp-oai]

Why

We already support running codex_core integration tests against an exec-server running under Wine, we should extend that support to app-server integration tests.

What

wine-exec app-server integration tests auto-generate a remote-only environments.toml and inject its Windows-native cwd into experimental thread starts when possible.

• add Wine execution-environment support to the app-server test harness
• register the selected remote executor through generated environments.toml and inject its target-native cwd where the protocol supports it
• skip unsupported cross-OS and local-only cases with follow-up TODOs, and cover the harness itself under remote runners

Caveats

The approach I've taken here is trying to balance a couple of goals:

1. getting as many existing and new tests to run against a windows exec-server by default
2. allowing app-server integration tests to explicitly test against particular environment setups

(1) argues for making the wiring as implicit/automatic as possible, but (2) means we can't automatically wire it up for literally every test.

Validation

Note that while this patch skips ~most app-server integration tests there are a few that definitely pass and use the exec-server (cmd+f "cwd" in this gist):

• command_execution_notifications_include_process_id
• thread_resume_replays_pending_command_execution_request_approval
• turn_start_updates_sandbox_and_cwd_between_turns_v2
