Persist agent stats across restarts, add per-tool metrics grid

Stats now survive daemon restarts via ~/.consciousness/agent-stats.json,
loaded into a global Mutex<HashMap> on first access. Each tool type
tracks last count, EWMA (alpha=0.3), and total calls.

UI shows a grid view: tool | last | avg | total, sorted by total desc.
Failures row appears at bottom if any occurred.

Also fixes temperature/priority not being applied to spawned agents.
