Test NanoClaw on Windows through WSL2

For each unexpected failure, preserve the test evidence, then follow the companion e2e-triage at a safe checkpoint and include its findings and next actions in the final E2E report. Research each distinct failure once, including when another E2E skill delegates here; do not delay active prompts, change acceptance results or submit public issues/comments without authorization. Install e2e-triage alongside this skill. If its relative link is unavailable, resolve it by skill name in the agent's installed catalog; if absent, report that triage was unavailable and continue the authorized test/report without installing anything implicitly.

Run this skill inside a fresh, disposable WSL2 Linux distribution, as its regular Linux user, from the NanoClaw checkout under test. Windows owns Docker Desktop; Ubuntu reaches its Linux engine through Docker Desktop's WSL integration. The checkout, home and test evidence belong on the Linux filesystem.
