fix: cleanup hooks not receiving error signal

[yxxhero]

Summary

• Fixes .Event.Error is not populated for cleanup global hooks #1041 by propagating errors to cleanup global hooks
• Changes withPreparedCharts callback signature from func() to func() []error
• Modifies TriggerGlobalCleanupEvent to accept an error parameter
• Updates all callback invocations to return errors

This fix ensures that .Event.Error is properly populated for cleanup global hooks when releases fail, matching the behavior already present for postsync release hooks.

Changes

1. pkg/app/run.go: Modified withPreparedCharts to capture errors from the callback and pass the first error to TriggerGlobalCleanupEvent

2. pkg/state/state.go: Updated TriggerGlobalCleanupEvent to accept an evtErr error parameter

3. pkg/app/app.go: Updated all callback functions to return []error

Test Plan

• Build compiles successfully
• make check passes
