fix(dashboard): compact run labels

[christso]

Summary

• Adds a shared Dashboard run display helper that returns primary text, secondary context, a one-line label, and tooltip/audit title text.
• Updates RunList table/mobile cards and Sidebar to use compact primary/secondary run labels instead of one long timestamp-heavy string.
• Preserves remote benchmark.json metadata.display_name in the run list so remote and local rows use the same friendly-name convention when the artifact provides one.
• Keeps Local/Remote source as the badge and preserves raw remote run IDs/display names in link title text.

Root Cause

Remote run metadata can surface timestamp-only display_name / run IDs such as 2026-03-27T05-00-00-000Z. The old formatter trusted that as the primary run name and then appended the formatted timestamp again, producing crowded labels like the reported remote screenshot while local runs with human display names looked fine.

The remote git-listing path also forced display_name to the run directory basename, so a remote artifact with metadata.display_name could still lose its friendly label before the Dashboard formatter saw it.

Reported evidence:

• Local better row: https://raw.githubusercontent.com/EntityProcess/agentv/e64364ce33b9fd4b1de5fcc0630f365300488d1e/docs/dogfood-reports/evidence/2026-06-08-av-fis-remote-sync/dashboard-unsafe-dirty-blocked-desktop.png

Validation

• bun test packages/core/test/evaluation/results-repo.test.ts (11 pass)
• bun test apps/dashboard/src/lib/run-label.test.ts apps/dashboard/src/components/RunList.mobile.spec.tsx (12 pass)
• bunx biome check packages/core/src/evaluation/results-repo.ts packages/core/test/evaluation/results-repo.test.ts apps/dashboard/src/lib/run-label.ts apps/dashboard/src/lib/run-label.test.ts apps/dashboard/src/components/RunList.tsx apps/dashboard/src/components/RunList.mobile.spec.tsx apps/dashboard/src/components/Sidebar.tsx
• bun --filter @agentv/core build
• bun --filter @agentv/dashboard build
• bun --filter agentv build
• Browser dogfood with isolated AGENTV_HOME / AGENTV_DATA_DIR and a throwaway local+remote fixture. API had a local display_name: local fixture run and a remote metadata.display_name: remote fixture run under a timestamp-only remote run directory; screenshots confirmed friendly primary labels for both, separate source badges, no horizontal overflow, and tooltip raw-ID auditability.
