nymph: add kanshi profiles for laptop / dock switching

Two profiles, auto-selected from connected outputs:
- solo: only eDP-1, all workspaces routed there.
- dual: eDP-1 + DP-1 (3440x1440@100Hz dock), workspace 1 on the laptop
  panel and 2-10 on the dock; each profile reissues swaymsg "workspace
  N, move workspace to output X" on activation so workspaces follow.

host.conf autostarts kanshi and drops the redundant gaps/corner_radius
overrides, leaving the base sway/config values in effect.
