herdr v0.7.3-ironin.2 — 7 opt-in additions + fixes

Combined opt-in feature set on top of herdr 0.7.3. Every feature is off by default and gated behind a config key — a stock herdr config behaves identically to upstream. Branch: ronin-release; each feature is also a standalone single-commit branch for upstreaming.

Changes since v0.7.3-ironin.1

• Scrollbar gained auto mode (show-while-scrolling, auto-hide) in addition to the original on/off.
• Agents panel gained a configurable toggle cycle (ui.agent_panel_modes) and a priority-sorted "space" view.
• Tab agent status now renders the exact same per-agent glyphs as the agents panel (⠋ working, ◉ blocked, ● done-unread, ✓ done-read, ○ unknown) and includes hook-only/report-only agents — the tab and panel show an identical agent set.
• New: reused-pane agent-detection fix; configurable server-stop timeout (with 0→default and an upper clamp).

All features are leak-free of any fork-internal naming in src/.
