Save detailed context about the current problem to a markdown file for handover to another session due to context limit reached.

1. **Create context handover file** in project root: `CONTEXT_HANDOVER_[TIMESTAMP].md`
2. **Document the current problem** being worked on with all relevant details and analysis
3. **Include current progress** - what has been discovered, analyzed, or attempted so far
4. **List key files examined** and their relevance to the problem
5. **Save current state** - todos, findings, next steps, and any constraints
6. **Stop execution** - context is now ready for a fresh session to continue the work
