Add dedicated actor detail page accessible from both web and TUI surfaces.
Web:
- /actor/<hex> page with live-updating stats, sparkline charts for message
rate and mailbox depth, status badge, worker assignment
- Actor addresses in overview and actors pages now link to detail page
- Actors page detail panel links to dedicated detail page
TUI:
- ViewMode::ActorDetail with per-actor sparklines (rate + mailbox)
- Enter on actor row opens detail, Esc returns to previous view
- Per-actor ring buffer history (60 samples) tracked in App state

Add in-process ring buffer history for per-worker and per-actor stats,
with sparkline rendering on both web (SVG) and TUI (ratatui) surfaces.
- history.rs: DashboardHistory with bounded VecDeque ring buffers, LRU
actor eviction, thread-safe RwLock, 4 unit tests
- SSE producer records stats every tick, sends initial history snapshot
- /api/history REST endpoint for on-demand history JSON
- Web: inline SVG sparklines in worker detail headers (rates + mailbox)
- TUI: per-worker Sparkline widgets in overview layout

Runtime dashboard now features a TUI option and an interface for LLM tool use. Removed some bloat from stats collecting and replaced with a hook function to dump runtime stats into.
