docs(readme): rewrite Pro section to match the website (voice, personas, actions)

Align the Pro block with the site's aspirational framing (website/mobile.md):
voice mode (Kokoro TTS), custom personas, draft-then-approve (Calendar/email/MCP),
and Sync landing through July. Fix stale pricing ($50 -> $69 lifetime / $49
annual, matching _data/pricing.yml) and drop the licensing sentence.

-The free OSS keeps shipping, MIT, forever - that's not changing. Pro is an optional, additive tier.
+Pro is an optional, additive tier. It gives the assistant a voice that talks back, personas you shape, and the tools to draft real actions you approve. One license covers your phone and your Mac. All on-device.
 
 ### What Pro adds
 
-- **Custom personas** - system prompts, voice, persistent memory per assistant
-- **End-to-end voice mode** - Whisper STT (already shipping) + Kokoro TTS, all on-device
-- **Calendar + email + MCP servers** - Linear, Notion, GitHub, your own MCP. Drafts only; you approve every send.
-- **Future Pro features** - included for the supported lifetime of the app
+- **Voice mode** - the free app transcribes your speech; Pro adds on-device Kokoro text-to-speech, so it talks back and you run the whole thing hands-free. The voice runs in your phone's RAM.
+- **Custom personas** - give each assistant its own system prompt, voice, and persistent memory, so it stays in character across conversations.
+- **Draft, then approve** - connect Calendar, email, and MCP servers like Linear, Notion, and GitHub. It drafts the reply or files the ticket and waits. Nothing sends without your tap.
+- **Sync, landing through July** - your phone and your Mac merge into one picture over your own network, never a relay. Your license includes it the day it ships.
