Do not send SW_RESTORE to a window that is not minimized.
ShowWindow($targetHwnd, 9) is SW_RESTORE. For a maximized window, SW_RESTORE returns it to its smaller restored size. This script also runs on the restore path, where $targetHwnd is the user's original window. A user whose editor or browser was maximized sees it un-maximize after every nudge, and up to three nudges run per test job.
Gate the call on IsIconic so a minimized target still wakes up and a maximized target keeps its state.

Fully qualify the TestMode type.
Both imported namespaces define TestMode. The ambiguous property cannot implement ITestAdaptor.TestMode, so the test assembly does not compile.

This recovers test jobs across domain reloads, adds a bounded per-job focus-nudge budget, and replaces the inline CI result gate with a tested checker. Two things I could not get past:

Description
Recover MCP test jobs whose callbacks are lost during a domain reload, and bound focus recovery so repeated polls cannot keep taking the user's desktop focus. Repair the Unity test and E2E checks so they exercise real tests and report failures accurately.
This PR targets

UNITY_MCP_DISABLE_FOCUS_NUDGE=1, share a bounded per-job retry budget across polling requests, and skip nudges when background execution is enabled.TestModeand implementITestAdaptor.Arguments.Related Issues
Validation
0abe62df: Python CI passed 1456 tests, 3 skipped, plus 202 tooling tests.Limits
The lifecycle fixture simulates persisted reload state and callbacks inside a real Editor. A physical mid-run reload on the reporter's exact Unity version and real Windows desktop focus activation/restoration remain unverified. The full supported-version CI matrix and release resumption have not been run. Platform-define compilation checks do not establish native macOS behavior.
Clearing an MCP job does not cancel Unity's physical test run. The existing five-minute stale cutoff and omission of complete terminal results from later reload persistence remain unchanged. Focus budgets are local to one Python server process.
Separate infrastructure follow-up: the Python tests passed, but the optional Codecov upload was rejected because a protected branch requires a token; coverage publication is not claimed.
