Checklist

• Tests pass locally (cd tests && npm test)
• If modifying skill descriptions: verified routing correctness with integration tests (npm run test:skills:integration -- <skill>)
• If modifying skill USE FOR / DO NOT USE FOR / PREFER OVER clauses: confirmed no routing regressions for competing skills
• Version bumped in skill frontmatter (if skill files changed)

Adds a new Dashboard panel that surfaces end-to-end (integration) pass rate per skill, including a visual percent bar and pass/fail grouping around a 70% threshold.

Changes:

• Adds a new “End-to-End Pass Rate per Skill” panel to the dashboard layout.
• Implements client-side fetching/aggregation/sorting of integration test results into per-skill pass rates.
• Adds styling for an inline percent bar with a 70% threshold marker.

• The 70% threshold is hard-coded in multiple places (comparisons + UI labels). Please centralize it (e.g., a single constant like E2E_THRESHOLD = 0.7 and derive thresholdPct = Math.round(E2E_THRESHOLD * 100)) to avoid future drift and make threshold changes safer.
