Consider compiled JsonPath execution plan #128

JsonPath evaluation currently walks the AST directly (interpreter-style).

We have some ongoing work in May 2026 to support two JDT versions:

1. The original Java 21 interpreted version, which is fine for one-time config loading, or infrequent code paths
2. A Java24+ bytecode generator that makes Java21 bytecode, which is for hot path validation, where the compiling can be ahead of time to deploy validators that were generated by a build system. (Yet it can of course also be run on demand in a JDK, yet hot deploy of new schema validators seems a rather niche use case.)

This ticket serves as a marker to follow the same patterns as the JSON Path engine. Have the interpreted version and a parallel bytecode-generated version that can be run as a build-time tool.
