fix: remove incorrect task persistence reference from Roo Code Cloud docs (#332)

* fix: remove incorrect task persistence reference from Roo Code Cloud docs

- Changed "task persistence" to "task sharing" in the main description
- Task persistence is not a feature of Roo Code Cloud - it works locally without cloud connection

* fix: also remove collaboration capabilities from the same paragraph

- Removed redundant "collaboration capabilities" as requested
- The paragraph now correctly lists: task sharing, usage analytics, and remote control options
