fix(pwa): handle orientation.lock() promise rejection silently

screen.orientation.lock() returns a Promise; the old try/catch only
caught synchronous errors, leaving the rejection unhandled and triggering
the auto-reporter (issue #8). Added .catch(()=>{}) to suppress it.
Also fixed CI: add sleep+retry around gh release create to avoid 502
race condition after delete.

Closes #8
