[Report] Cross-Team Dependencies - "Where are teams waiting on each other?"

[thefactremains]

Summary

New VISTA report that maps dependency relationships across Percona product teams, showing where one team's work is blocked by or dependent on another team's deliverables.

User Stories

• As a PM, I want to see "Where are teams waiting on each other?" to identify coordination risks.
• As the Operators team lead, I want to know if MySQL has shipped the Binlog Server milestone I need for PITR.
• As a docs writer, I want to see which features are approaching release so I can plan documentation.

Data Source

Jira issue links (blocks/is blocked by, depends on, relates to) and labels. Already available via Claude MCP connection.

Report Contents

• Dependency graph/matrix showing cross-team relationships
• Blocked items with team attribution (e.g., "Operators blocked on PS-10479 owned by MySQL")
