fix: capture ios device logs with devicectl console

[thymikee]

Summary

Capture iOS physical-device app output by launching the session app through xcrun devicectl device process launch --console --terminate-existing, avoiding the rejected device log stream --device path on devicectl 506.6.

Keep the clear unsupported fallback only for toolchains that do not expose console capture, and report that capability in logs doctor. logs path/logs doctor still surface failed startup state instead of letting marker-only logs look active.

Closes #1022

Validation

Passed local checks: pnpm exec vitest run src/daemon/__tests__/app-log.test.ts src/daemon/handlers/__tests__/session.test.ts src/utils/__tests__/args.test.ts --testNamePattern "logs clear --restart starts active|logs clear --restart requires|runAppLogDoctor|startIosDeviceAppLog|buildIosDeviceConsole|usageForCommand resolves debugging"; pnpm format; pnpm check:quick; pnpm check:fallow --base origin/main; pnpm check:unit; pnpm build.

Physical-device verification used thymikee-iphone / UDID 00008150-001849640CF8401C. I ran pnpm test-app:start -- --port 8081, kept Expo/Metro visible, then opened com.callstack.agentdevicelab with session issue-1022-console-logs. logs clear --restart, logs mark, logs path, and logs doctor showed an active ios-device backend with devicectlAvailable: true and devicectlConsoleCapture: true; the bounded app.log window contained real app output including the Metro bundle request and ReactInstance: evaluateJavaScript() with JS bundle, not only marker entries. snapshot -i on the same session showed the Agent Device Tester RN home screen.

Manual cleanup: closed issue-1022-console-logs and stopped the Expo process.
