revert: remove brittle string-matching catches and alias comments in browser-manager

Revert 6 catches that matched error messages via includes('closed'),
includes('Target'), etc. back to empty catches. These fire-and-forget
operations (page.close, bringToFront, dialog dismiss) genuinely don't
care about any error type. String matching on error messages is brittle
and will break on Playwright version bumps.

Remove 6 'alias for active session' comments that existed solely to
game slop-scan's pass-through-wrapper exemption rule.
