fix(screenshot): Recycle bitmap copy on masking failure to prevent memory leak

When an exception occurred in applyMasking after creating a mutable
copy of the bitmap, the catch block returned the original screenshot
without recycling the copy. This caused bitmap memory to accumulate
until GC runs, potentially causing OOM issues on frequent errors.
