refactor(system-prompt): rename TOOL_ORDER_REST from '...' to '<unlisted-tools>'

A three-dot rest entry reads as elision in a cordis.yml; the spelled-out
sentinel says what lands there. The literal now appears once in code (the
constant) and once in the value-pinning test; every other reference — the
forwarding tests included — imports TOOL_ORDER_REST, which adds the
dsh-system-prompt devDependency to the two app packages.

Review follow-up on #196.
