fix(finishing): name the actual files in the refusal prompt
`git status --porcelain` collapses a wholly-untracked directory to a single
`?? docs/` line. In the shape of the incident this step exists for (#2016 — an
uncommitted plan document under an untracked `docs/` tree), the file list we
show the human partner therefore names no file at all:
$ git -C "$WORKTREE_PATH" status --porcelain
?? docs/
$ git -C "$WORKTREE_PATH" status --porcelain -uall
?? docs/superpowers/plans/2026-08-04-csv-export-rollout.md
Both forms produce identical (empty) output on a clean worktree, so this adds
no over-trigger surface.
Found while running this PR's behavioral micro-tests. Every treatment agent
dug past `?? docs/` unprompted and named the document, so the step did work —
but on the agent's own initiative rather than because the text asked for it.
That initiative is not reliable one tier down: Claude Haiku 4.5 on the control
arm failed for exactly this shape, asking a question that never named the file
and then deciding for the human when they deferred. Nothing in the prior
wording stopped a treatment agent from relaying `?? docs/` verbatim and
satisfying the letter of the instruction.
Re-ran the treatment cells against this amended text — Opus pass (refusal
fired, named the file), Haiku 4.5 pass (named the file) — no regression.
