The old workspace-review prompt only hunted for catastrophic bugs and
omitted everything it wasn't highly certain about, so it usually returned
'No high-signal issues found' and felt useless.
Rework it to first understand the diff's intent and judge whether the
implementation actually achieves it and is adequate (smallest correct
solution, completeness), then review correctness across concrete failure
modes (concurrency, lifecycle, state fanout, comparators, a11y,
regressions, targeted-test gaps) plus a security/supply-chain lens, and
classify findings by severity (blocker / non-blocker / nit). Keeps the
existing false-positive discipline (diff is source of truth, validation
pass, no nitpicks, cite rules) and stays review-only by default.
Adapted from a battle-tested PR-review prompt, minus the GitHub-specific
parts that don't apply to a local workspace diff. Updates command and
settings descriptions across locales.
