Add typed numeric wrappers and precise number mode to gremlin-javascript

[kirill-stepanishin]

Summary

JavaScript's single Number type (IEEE 754 double) loses the distinction between JVM numeric types like int, float, long, and double. This PR gives gremlin-javascript users explicit control over numeric type fidelity on both sides of the wire.

Serialization — New wrapper classes and factory functions (toInt, toFloat, toDouble, toLong, toShort, toByte) control the exact GraphBinary type code and GremlinLang suffix sent to the server. Without wrappers, existing type-inference behavior is unchanged.

Deserialization — A new numberMode: 'precise' connection option wraps incoming numeric values in the same typed wrappers, preserving the server's original type information. Wrappers support transparent arithmetic via valueOf/Symbol.toPrimitive, and an unwrap() helper extracts raw values.

Implementation — Refactored GraphBinary.js IoC initialization into a createIoc() factory so precise mode can inject a postDeserialize hook via AnySerializer. Extended NumberSerializationStrategy and GremlinLang to route wrapper instances to the correct serializers/suffixes. Enhanced Long to accept bigint with full int64 range validation.

Tests

• Unit: type-code routing, byte-level verification, round-trip serialize/deserialize for all six types, precise-mode coverage (nulls, nested structures, non-numeric passthrough), GremlinLang emission for all wrappers including edge cases (NaN, ±Infinity, boundary values, predicates, collections)
• Integration: precise mode against a live server verifying Int/Double wrappers on vertex properties and edge weights
• Export verification for all new public API symbols

Documentation

• Reference docs: new "Numeric Types" section, updated connection options table and limitations
• Upgrade guide: new "JavaScript Typed Numeric Wrappers" section
• CHANGELOG entry

How many modes are there? If it's only precise or not can we rename the option and make it a boolean?
