Keep native /start-work resolvable on Sisyphus, but switch the work session back to Atlas when Atlas is registered. Stamp the outgoing agent with Atlas's actual list-display key so config→start-work execution resolves correctly and still falls back to Sisyphus when Atlas is unavailable.

/start-work should leave plan mode even when Atlas is unavailable. This prevents Prometheus from being persisted into boulder state and keeping resumed work sessions in md-only mode.

When no worktree is specified in boulder, stop injecting 'Worktree Setup Required'
instructions. When worktree IS present, inject emphatic instructions ensuring the
agent and all subagents operate exclusively within the worktree directory.
