[Bug] Reduced Context Retention and Intelligence in Code Generation

Bug Description
reduced intelligence and context issue is back

completely missed major parts of a plan that was created after compaction.

i had given cc a task to enhance a plan and during the audit, compaction occured. after the compaction it lost context and created a new plan isntead of enhancing the older plan that i had asked it to enhance and missed out major parts of it. im assuming that in the compaction process it missed reading the main file.
