Description
Missing builtins
glob.matchglob.quote_meta
Context
These OPA builtins are not implemented in the SDK. Most are exercised by the Rego compliance suite (opa-evaluator/src/test/resources/compliance/.../TestData) and currently raise FunctionNotFoundError; implementing them makes those cases pass.
Implementation notes
Register each builtin with an @OpaBuiltin-annotated static method (see io.github.open_policy_agent.opa.ast.builtin.impls). Core builtins are listed in BuiltinRegistry.BUILTIN_CLASSES; domain-specific ones live in an opa-builtins-* module exposed via the BuiltinProvider SPI (e.g. RegexBuiltins, CidrBuiltins, SemverBuiltins).

Research direction
Start with the existing builtin implementations under io.github.open_policy_agent.opa.ast.builtin.impls and inspect BuiltinRegistry.BUILTIN_CLASSES, then compare the compliance cases under opa-evaluator/src/test/resources/compliance/.../TestData. Register implementations for glob.match and glob.quote_meta using the documented builtin annotation and verify the affected compliance cases no longer raise FunctionNotFoundError.
