Problem
Omniparser previously used a single element mapping derived from the most recent
screenshot to convert all historical computer_call messages. This caused incorrect
element IDs when UI state changed over time.
Solution
This PR builds element ID mappings per screenshot and applies the most recent
prior mapping when converting each message. This preserves historical UI context
and prevents incorrect element ID assignment.
Impact
fixes #694
