💡 What: Pre-compute and cache the lowercased version of the task title (titleLower) during the parseTask data transformation phase instead of computing it dynamically in taskHasOpenPR.

🎯 Why: taskHasOpenPR is called in a tight loop for every single task retrieved from the Jules API. Running .toLowerCase() repeatedly on the same string within these loops leads to redundant string allocations and garbage collection overhead, slowing down the filtering operations on large data sets.

📊 Impact: Reduces CPU cycles and memory allocations during cross-reference filtering when determining which tasks can be archived. The optimization avoids O(N*M) string allocations (where N is the number of active tasks and M is the number of open pull requests).

🔬 Measurement: Verified by ensuring the background.test.js unit tests for parseTask and taskHasOpenPR execute correctly. Since the optimization prevents the repetitive creation of string objects, the improvement scales with the number of tasks in the user's workload queue.


PR created automatically by Jules for task 2135849071654453457 started by @n24q02m

- Compute and cache `titleLower` during `parseTask`.
- Update `taskHasOpenPR` to leverage the cached `titleLower` property, avoiding repetitive `.toLowerCase()` string allocation overhead during orchestrator loops.
- Update tests to account for the new pre-computed property.
