fix(ci): soundness gate must not assume bare dune on PATH (greens main)

[hyperpolymath]

Greens main, which #633 left red.

Root cause

The soundness gate's property 5 ran dune build test/xfail/test_xfail_pins.exe. CI reaches dune only via opam exec -- dune, not bare dune on PATH, so this failed with "ERROR (property 5): cannot build test/xfail/test_xfail_pins.exe" — and the build job exited there (before @fmt). It greened locally because my dev box has dune at /usr/bin/dune; that environment difference is exactly what a local-only run can't catch.

Fix

The harness exe is already built by the dune build / dune runtest steps that run before the gate, so the gate now prefers the pre-built binary (_build/default/...) and only builds — with whatever dune is available (dune, else opam exec -- dune) — if it's missing. Fail-closed if it still isn't there.

Verified (the actual CI condition, not just locally)

Built the exe, then ran the gate with dune/opam removed from PATH:

dune on restricted PATH? NO
OK: soundness ledger — all 5 properties hold (...)
rc=0

Note

#633's build died at this gate, so @fmt never ran on its lib/*.ml edits (the return-fence). With the gate fixed, CI here will reach @fmt; if it flags those lib edits I'll follow up (I can't run ocamlformat in my environment, so I'd apply the diff from the CI log).
