test(scoping): stop pinning a purgeable trash archive

The seam asserted `[ -f scripts/.AGENTTRASH/chat-template.jinja.ik-llama-qwen-sharp ]`
so that the planning assertion "could not pass by the file having vanished". That
reasoning was wrong twice over: the planner's rule is a PATH rule, so it plans
nothing for that path no matter where the bytes sit, and the trash is a purgeable
hold — #111 untracked it, so a fresh worktree or CI checkout has no such file and
the suite went red on a byte that carries no meaning.

Measured: fresh worktree off origin/main, deployment_scoping.bats:39 fails. After
the change: that file 28 ok / 0 fail, ./tests/run.sh 789 ok exit 0.
