Subject: [PATCH] conformance: select ast-id alongside ethdebug for solc

solc's develop branch rejects `debugInfo: ["ethdebug"]` since
argotorg/solidity#16961 (merged 2026-09-19): "To use 'ethdebug' with
settings.debug.debugInfo you must select also 'ast-id'." Every
conformance run against a solc built after that date fails at
compilation. The adapter now selects both.
