LGUG2Z 3e21ebd3a4 feat(e2e): windows-nextest runs the Windows unit tests in the guest
The Windows crates' unit tests could only run in the (future) hosted Windows
CI. They run in the existing Windows e2e guest: nix run .#windows-nextest
boots the golden image like a scenario (restoring a saved state when
KOMOREBI_E2E_STATE is set), uploads the test executables that the check
windows-nextest-build cross-compiled, runs every test in a process of its own
(nextest.exe is not needed: komorebi's tests share global state, so one
process per test is what nextest does too) and prints a line per executable
and the failures, with OUT/cargo-tests.json for every result.

The driver e2e/platforms/qemu_windows/cargo_tests.py already existed and was
wired to nothing; it now takes the check output (tests.tsv) as well as cargo
messages, creates the saved state itself, prints the panic message of a
failure, and uploads the data files the tests read. Those are found by the
CARGO_MANIFEST_DIR baked into the executables, a path of the Nix build, so
the check also keeps schemas/ and the tests' fixtures and the driver puts them
at that path under C:. Without them 20 tests failed for the missing files.

docs/dev/build-and-test.md and docs/dev/flake-checks.md describe the check,
the app and the neutral crates in linux-nextest.

Verified: nix run .#windows-nextest on the golden image g8 (scale 1.5, state
~/e2e-w0/state-nextest): 964 tests in 37 executables, 964 passed, 0 failed,
202 s with the state restored (first run 163 s more to save the state).
One run only; not soaked. No e2e scenario, the golden image or the existing
e2e-windows behaviour changed.
