Pull request overview

This PR introduces a new "ok_rate" metric to the LSP benchmark system to distinguish between request reliability (whether requests complete without timeout/error) and accuracy (whether requests return valid definition locations). The ok_rate metric provides visibility into timeout/error rates separately from the existing success_rate metric.

Key Changes

• Added ok_rate calculation and tracking to aggregate statistics alongside success_rate
• Created a backfill script to retroactively add ok_rate to existing benchmark JSON files
• Updated the web dashboard to display ok_rate with a new chart and table column
