- one running tracker (Combatant rows); no encounters to manage
- Enemies list gets a "Track" column (checkbox + count) and an
"Add to tracker" button; picking N of an enemy makes "Goblin 1..N",
numbering continues if some are already on the tracker
- /tracker: per-combatant current/max HP with an HP bar, Damage / Heal
by amount, remove one, "Clear all". HP is clamped to [0, max];
0 HP shows a "Down" badge. Stats are snapshotted from the Enemy on add.
- "Tracker" nav item; tracker_picker Stimulus controller; app.js gains a
data-format="pick" cell renderer
