fix(aws): defer Android app launch until open

[dennisimoo]

Summary

AWS Device Farm Android sessions now create Appium with appium:autoLaunch=false by default. The existing open lifecycle still activates the requested package after allocation, but first-run system activities can no longer make WebDriver session creation fail before agent-device gains control.

This changes 2 files (+15/-1). Other providers and iOS behavior are unchanged; explicit internal capability overrides still win.

Validation

Tested commit fdab96c27afe40bcd5432ed110ffc6353aee4686:

• pnpm check:affected --run — all runnable checks passed
• 102 related test files / 588 tests passed
• Regression test failed before the implementation (autoLaunch was undefined) and passes after it

GitHub remains authoritative for the listed live/device lanes.

🔵 Needs a closer look

Add a regression test verifying that an explicit appium:autoLaunch: true override wins.

• This regression test only exercises the default path. The merge order on lines 248–250 is the part that guarantees an explicitly configured appium:autoLaunch value still wins, so add a case that passes webdriverCapabilities: { 'appium:autoLaunch': true } and asserts true; otherwise a future change that reverses the spreads would silently break the documented override behavior.

  assert.equal(prepared.webdriverCapabilities['appium:autoLaunch'], false);

No code findings at fdab96c. The Android default reaches WebDriver session creation, explicit overrides still win, and open retains the later app activation. Before this is ready, please provide a live AWS Android run that allocates a session with autoLaunch=false, opens the requested package successfully, and cleans up the session; the capability-construction test does not prove that provider lifecycle. There are no conflicts, and GitHub currently reports no checks for this head.
