GitHub Backed Report Dedupe

Initial Debt

Codex review found that database-backed reports with a githubUrl could appear twice after backoffice merged local database rows with live GitHub issue rows.

Why It Matters

Normal CLI reports with repository metadata could inflate open report counts and show duplicate triage rows: once from harnessReport and once from fetchGitHubReportIssues().

Resolution

Backoffice report aggregation now deduplicates rows by githubUrl and prefers the live GitHub-sourced row when a database row and GitHub row refer to the same issue.

Validation

• bun run --cwd apps/api test -- backoffice.test.ts reports.test.ts

Closeout

Resolved in PR #24 follow-up after Codex review.
