Subject: [PATCH] Split generated deserializer constructor for large schemas
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

When a schema has many fields with distinct complex types (e.g., 1000+
fields each containing a unique record type in a union), the generated
FastDeserializer constructor can exceed the JVM's 64KB method bytecode
limit, causing a "code too large" compilation error.

The existing method-splitting logic (populate_ helpers) only applies to
the deserialization methods, not the constructor. This change applies the
same splitting pattern to the constructor: every 500 schema variable
declarations, a new initSchemaFields_N() helper method is created, and
the constructor delegates to these helpers.

Changes:
- Add SCHEMA_VARS_PER_CONSTRUCTOR_METHOD constant (500)
- Track constructor body separately to redirect assignments to helpers
- Drop FINAL modifier on schema fields to allow assignment in helpers
- Add test with 1000 fields × 5 sub-fields of distinct record types
