v2.12.3

Fixes:

• array() now reports up to 3 errors, instead of only the first one
• record() and mapping() now stop after 3 errors, so huge invalid inputs can no longer build cause perf issues
• Standard Schema issues and formatShort() no longer repeat the array index in the message itself (it's already part of the reported error path)
• Standard Schema issues and formatShort() no longer report a bogus index 0 issue for array items with only nested errors
