1. Shell actuator: remove double bash -c wrapping (format ~s produces
S-expression-safe strings, not shell-safe). Now passes cmd directly
to (timeout N bash -c cmd) via run-program arg list.
2. Dispatcher: extend high-impact approval gate to :system :eval.
Previously only :shell, :tool "shell", and :emacs :eval triggered
HITL. Now :system :eval also requires Flight Plan approval.
3. Skill sandbox: before promoting a skill from its jailed package to
:passepartout, scan for restricted symbol references (uiop:run-program,
uiop:shell, uiop:run-shell-command). Block promotion on violation.
New skill-entry status :sandbox-blocked for blocked skills.
Test: 91 pass, 0 fail across 13 suites.
