Append a "⊙ goal 3/20" segment (turns used / turn budget) to the CLI
status bar whenever a standing /goal is active. Mirrors the desktop
composer goal indicator: active-goal-only — paused/done goals stay out
of the bar since they already print their own glyph lines in-thread.
- Snapshot: goal_active / goal_turns_used / goal_max_turns from the
cached GoalManager (in-memory attribute read, no DB hit per repaint).
- Rendered in all three width tiers of both _build_status_bar_text and
_get_status_bar_fragments, and it respects the /statusbar toggle for
free (the toggle gates _get_status_bar_fragments as a whole).
- Tests: segment composition, active-only contract, all width tiers.
Status-bar goal indicator concept from #43020.
