Melee: surface weapon state across maps; reset stale caches

- Map transitions often leave a non-crowbar weapon active, so the killbot
  silently does nothing. Log every active-weapon change as a normal
  `melee: active ... crowbar=0/1` line and toast once suggesting the crowbar.
- Recover the crowbar model from the server entity when the client weapon
  model index is missing/0 after a map change.
- Clear the bone cache and aim/silent locks when the local player entity
  changes (map load/respawn) so stale entity/model data cannot poison melee
  target selection.
