Greptile Summary

Applied the same tooltip singleton management pattern from LinearIssuePreviewTooltip to JiraIssuePreviewTooltip. This ensures only one tooltip can be open at a time across all Jira issue preview instances.

• Added module-level singleton activeTooltipForceClose to track the currently open tooltip
• Implemented controlled tooltip state with open and delayed close timing (300ms)
• Added mouse enter/leave handlers on both trigger and content to prevent premature closing
• Used React refs pattern for stable force-close callback across renders

Confidence Score: 5/5

• This PR is safe to merge with minimal risk
• The implementation directly mirrors the proven pattern from LinearIssuePreviewTooltip. The changes are purely additive UI improvements with no impact on business logic, data, or external systems. The singleton pattern is correctly implemented with proper cleanup handlers.
• No files require special attention
