Fix Summary: Rod Library Nil Map Panic

Problem

The cremote daemon crashed with panic: assignment to entry in nil map when calling WaitLoad() on a page object.

Root Cause

This is a known issue in go-rod v0.116.2 (https://github.com/go-rod/rod/issues/331).

When pages are retrieved using browser.Pages(), they are not fully initialized - internal maps are nil. When methods like WaitLoad() try to use these pages, they panic.

Solution

Modified daemon/daemon.go to properly initialize pages retrieved from browser.Pages():

Changes in findPageByID() (lines 2363-2400):

• Added defer/recover to catch initialization panics
• Call p.Info() to initialize internal page state
• Return error if initialization fails
• Added detailed comments explaining the issue

Changes in getTab() (lines 2428-2448):

• Set up console logging for pages found via findPageByID
• Added debug logging when caching existing tabs
• Added comments explaining when this code path is used

Files Modified

• daemon/daemon.go - Added page initialization and error handling
• error.md - Documented the issue and fix

Testing

✅ Code compiles successfully ✅ Proper error handling added ✅ Panic recovery in place

Next Steps

1. Test with a scenario where daemon is restarted while browser is running
2. Verify that pages are properly initialized before use
3. Monitor for any similar panics in production
