fix(dock-engine): improve window activation to target the correct window

Old logic matched only by X coordinate with 3px tolerance, which fails
for multi-window apps like IntelliJ IDEA where windows have distinct
titles but may share similar X positions.

New two-pass matching strategy:
- Pass 1: exact AX title match against the CGWindowName of the target
  window (covers IDEA project windows, Chrome tabs, etc.)
- Pass 2: position match using both X and Y within 8pt tolerance as
  fallback for untitled or same-title windows

Also resolve the owning PID from CGWindowInfo so that multi-process
apps activate the correct process instance.
