Subject: [PATCH] chore(.dev): run wrapper from REPO_ROOT, not .dev/
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

When the agent does `gh pr checkout <stale-PR>` on a Dependabot
branch forked before `.dev/` was merged to main, `.dev/` is
unlinked from disk. If the wrapper's cwd is `.dev/`, the shell's
$PWD becomes a dead inode and every subsequent command — including
the queue's `gh pr list` — fails with "Unable to read current
working directory."

Switch the wrapper to cd into REPO_ROOT at startup and reference
prompt files via $SCRIPT_DIR/. REPO_ROOT survives any branch
switch the agent makes inside its session.

This also fixes the agent's own bash cwd (it inherits the wrapper's
cwd via the claude subprocess), so the dance where the agent had
to spawn a worktree subagent as a workaround goes away.
