Subject: [PATCH] fix(evals): destructive-actions guard actually inspects Bash
 commands
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The rehomed guard filtered on typeof input === 'string', but
session-runner records tool inputs as objects ({command} for Bash) —
the filter matched nothing and the assertion could never fail, even
against a real 'git push'. Now extracts the command from the object
shape, same as the usedGitDiff check above it.
