Subject: [PATCH] perf(hooks): reduce PowerShell spawns from 3 to 1 per
 notification

Merge findPowerShell version check and isBurntToastAvailable check
into a single notifyWindows call. Now just tries to send directly;
if it fails, tries next PowerShell path. Version field was unused.

Net effect: up to 3 spawns reduced to 1 in the happy path.
