#170 UI: single-source the version from package.json + refresh About

[AlvinShenSSW]

Closes #170.

Problem

The version in the app top-right and the About card was hardcoded v3.0.0-dev, so it stayed at 3.0.0 while #167 bumped tauri.conf.json / package.json to 3.1.0 — two independent version sources that drift.

Fix

• Single source: inject the version from package.json at build time (Vite define __APP_VERSION__, imported via resolveJsonModule so no @types/node is needed) and render v{__APP_VERSION__} in both App.tsx and Settings.tsx. The label now always matches the packaged release.
• About refresh: rewrote the blurb (zh + en) to reflect current V3 scope — agent/Hub fleet; CPU/RAM/GPU/VRAM; LADA 4K per-task progress + ETA; ComfyUI; AI-coding activity (Claude/Codex/Kimi); privacy-first — and credit the sole designer/developer (Designed & developed by 304 / 由 304 独立设计与开发).
• Test: asserts the rendered label equals __APP_VERSION__ (not a literal), so it can never drift again.

Verification

npm run build bakes v3.1.0 into the bundle; npm test 73 passed (incl. the new version test); eslint clean (no new warnings).

Claude implement + TDD. External gates run automatically: Codex 外门 then Kimi 终审. Leave-open (owner merges).

Review trail (/afk — Claude-driven)

• Codex 外门: CLEAN — "consistently injects the UI version from package.json via Vite and updates both views; build, tests, and lint completed without errors attributable to this patch."
• Kimi 终审: VERDICT: PASS. No blockers. Confirmed: the define produces a string-literal replacement (not a bare identifier); the vite-env.d.ts global is correctly typed; resolveJsonModule makes the JSON import type-check; vitest reuses the config so __APP_VERSION__ is defined in tests; zh/en i18n parity maintained; the test asserts against __APP_VERSION__ itself → drift is impossible. Non-blocking nits (optional App.tsx-site test, toBeInTheDocument style, pre-existing spy cleanup) accepted as-is — the second is inconsistent with this file's non-jest-dom style; drift is already structurally prevented.

CI green. Leave-open (owner merges).
