Validate number length when coercing String to double

[aysha-afrah26]

When a JSON string is coerced to a double, the value goes through StdDeserializer._parseDoublePrimitive, which hands the text straight to the double parser. Its sibling _parseFloatPrimitive, right above it, first checks NumberInput.looksLikeValidNumber and then calls streamReadConstraints().validateFPLength() so the configured maxNumberLength limit applies before parsing, but the double variant skips both. The effect is that float[] rejects an over-length numeric string while double[], OptionalDouble, and the general String-to-double coercion accept it, so a length limit the user configures is not honored on those paths. I noticed it while comparing the two primitive helpers, since every integer-family helper in the same class already validates length the same way. The fix applies the same pre-validation to the double path so both behave alike. Added a test in the deser/dos package covering double[], alongside float[] which already enforces the limit.

Code Review ✅ Approved

Adds validation of number length when coercing String to double, matching the behavior already implemented for float and all integer-family helpers. This ensures the configured maxNumberLength limit is consistently enforced across double[], OptionalDouble, and general String-to-double coercion paths. No issues found.
