docs: shift core messaging to AI voice keyboard, voice double, agentic skills

Lead with “Say it. It's typed. Speaks like you. Acts for you.” across the
README and product page: the personalization story (learned style,
three-tone replies) moves ahead of typing, clipboard skills are framed as
agentic actions, and typing becomes the fallback capability.

 ### Changed
+- **Messaging shift to AI voice keyboard / voice double / agentic skills**: README and the product page now lead with “Say it. It’s typed. Speaks like you. Acts for you.” — the personalization story (learned style, three-tone replies) moves ahead of typing, clipboard skills are framed as agentic actions, and typing becomes the fallback capability. / **宣传定位转向 AI 语音键盘 / 嘴替 / Agentic 技能**：README 与产品页改用「开口即文字。会说你的话，会办你的事。」定位；个人化卖点（专属风格、三语气回复）提前，剪贴板技能表述升级为 Agentic 行动，打字退为兜底能力。
 - **Product page redesign**: rebuild the GitHub Pages home as a dark product stage with the new Icon Composer app icon, the three-device hero visual, and real on-device videos and UI cards replacing hand-drawn mockups; add 2.1 selling points (personal style, three-tone replies, monthly usage calendar, EventKit skills export, guided trials and credit rewards), a TestFlight link, and self-hosted inline SVG icons; bump page references to 2.1.0. / **产品页重设计**：GitHub Pages 主页改为深色产品舞台，启用 Icon Composer 新图标与三端同框主视觉，以实机视频与真实界面卡片取代手绘示意；补齐 2.1 卖点（专属风格、三语气个性回复、月度用量日历、EventKit 技能写入、引导体验与积分奖励），新增 TestFlight 入口，图标改为自托管内联 SVG；页面版本号更新至 2.1.0。
 - **Host-only analytics recording**: the keyboard extension no longer opens the analytics or keyboard-usage SQLite queues. The host app is the only process that records and uploads events, so hiding the keyboard cannot hold WAL locks and get killed as `0xdead10cc`. Keyboard-activated and per-keystroke usage events are no longer collected. / **仅主 App 记埋点**：键盘扩展不再打开统计与键盘用量 SQLite 队列；开库、记账与上传只在主 App 进行，收起键盘时不会因 WAL 锁被系统以 `0xdead10cc` 终止。不再采集「键盘激活」和逐次按键用量。
