Summary

Fix the two existing Windows failures in doctor.test.ts caused by Copilot fixtures hard-coding POSIX /tmp/... paths.

The tests are path-sensitive: on Windows, the production path resolver normalizes COPILOT_HOME to a native path while the mock setup still compares it with the POSIX fixture path. This made the tests report:

• standalone Copilot hooks under COPILOT_HOME as missing;
• a project Copilot installation check as present when only .github/hooks was configured.

This change uses os.tmpdir() and path.join() for the affected fixtures. It is test-only and does not change Copilot runtime behavior.

Validation

• npx vitest run src/__tests__/doctor.test.ts: 69 passed
• npm run lint: passed
• npm run typecheck: passed
• npm run build: passed
• git diff --check: passed

No findings in the specified diff.

The changes are test-only: they replace hard-coded POSIX fixture paths with path.join(os.tmpdir(), ...). The PR description documents sufficient validation; no end-to-end / real-CLI record is required for a tests-only change.

Review was read-only; I did not run, build, or install anything.

Approving at 276081b. The two Copilot fixtures now build their paths with path.join(os.tmpdir(), …), so on Windows they match the native path the resolver returns for COPILOT_HOME. It is test-only and changes no runtime behaviour, and CI passes on every OS at this head. On a merge with main after #1474, which also changes doctor.test.ts, the file passes 72/72.
