Function removeShadowedSessionEventEnumsForPython

scripts/codegen/python.ts:1197–1232

* Remove locally-emitted Enum class definitions whose name already comes from * a `.session_events` import. * * Quicktype's enum-merging path collapses structurally-identical enums (even * with `combineClasses: false`, which only governs class merging). When the * RPC schema gains sibling enums

(
    code: string,
    importedFromSessionEvents: Set<string>,
    sessionEventsSchema: JSONSchema7 | undefined
)

 * strip the local class so references resolve to the import.
