feat(ios): launch via XCTest with env vars for hierarchy/tap access (#39)

* feat(proto): add env map to LaunchRequest

* feat(driver): add env param to Launch interface and all implementations

* feat(sidecar): add IosDriverBackend using Maestro IOSDriver + env pass-through

* feat(testrun): launch iOS app via XCTest with env vars instead of simctl

* fix(ios): replace LaunchApp with BootedUDID; simctl launch moved to XCTest path

* test(cli): add tests for ios platform flag and ios-device flag parsing

* fix(sdk-ios): check semaphore wait result; resolve port from args and env; register extractors before start
