fix: Robust Cloudflare detection to prevent Playwright frame crashes

- src/cloudflare.js: Add try-catch around each locator operation in isCloudflareChallenge
- src/cloudflare.js: Add waitForLoadState before checking for Cloudflare
- src/cloudflare.js: Remove redundant outer try-catch (unreachable code)
- epic-claimer-new.js: Add delay after page.goto before checking Cloudflare
- epic-claimer-new.js: Wrap isChallenge() call in try-catch

Fixes: TypeError: Cannot read properties of undefined (reading 'childFrames')
