#148

What to build

Final ship of v0.2.1 dashboard. Closes #148.

• Cleanup: delete every old view/component no longer referenced (audit via grep + ESLint unused-imports). No // removed comments per project convention.
• Final test pass: ruff format --check && ruff check && npm --prefix ui run test:e2e clean
• Merge feat/dash-v2-rework → main
• Tag v0.2.1-alpha.1 — NOT marked prerelease so /latest resolves (per prior pattern from v0.1.0-alpha launch)
• Promo screenshots: regenerate via γ-suite Playwright harness (apiMock + sseHarness fixtures + throwaway spec capturing dashboard / slots / models / firstrun states)
• Docs sync: README + PLAN + hal0-web CONTENT_BRIEF + Astro pages reflect v2 dashboard
• Epic close: comment on parent v0.2.1: Vue dashboard retarget + slot-state polling from /v1/health #148 with cutover summary + link to v0.2.1-alpha.1 release

• No dead view/component code remains
