omi-windows-v1.0.0

## Omi for Windows — v1.0.0 (preview)

First Windows build of Omi — an Electron + React desktop port of the macOS app. Source lives at [`desktop/windows/`](https://github.com/BasedHardware/omi/tree/main/desktop/windows) on `main`.

### Install
1. Download **`Omi-for-Windows-Setup-1.0.0.exe`** below and run it.
2. Windows SmartScreen will warn that the publisher is unrecognized (the build is **not code-signed** yet). Click **More info → Run anyway**.
3. Launch Omi and sign in with your Google/Omi account.

> Per-user install (no admin needed). 64-bit Windows 10/11.

### What's in it
- **Always-on recording** via `/v4/listen` (mic + system audio) → conversations with auto title + emoji, live transcript, "Save now" / 30s-silence finalize
- **Screen-OCR ambient context** for chat and a floating **Ask overlay**
- **Rewind** local screen timeline with text search (on by default, ~1 frame/sec, stored locally)
- **Desktop automation** (FlaUI helper) — every action gated behind a native approval dialog
- **Google (Gmail/Calendar) OAuth** integration, sticky-notes import, app/file indexing
- Onboarding **brain map** (R3F / d3-force)

### Notes
- Recordings sync to your Omi account; screen/Rewind data stays **local** on your machine.
- No code-signing certificate yet → SmartScreen warning on first run (see install step 2).
- Built from `main` (`desktop/windows/`), including the packaged sign-in fix and security hardening merged in #7833.
