Clarify stop-inference data loss warning

Improves the recording-stop confirmation text to clearly state that standard recording-stopped save hooks are bypassed, saving depends on processor stop handling, and unsaved processor data may be lost or unpaired. Also adds an inline code comment documenting that reset does not trigger normal recording stop/save hooks.
