fix: prevent effect restarts when options are unchanged

[phh235]

What does this PR do?

Prevents unnecessary effect restarts when setOptions() receives values identical to the current configuration.

This adds an early-return check across 22 vanilla effects, avoiding redundant canvas/WebGL reinitialization and improving runtime stability and performance.
