docs: README — logo, real TestFlight link, drop Status, expand Privacy

- Logo and a TestFlight download badge at the top.
- Removed the Status/phase checklist — CLAUDE.md already tracks this,
  duplicating it in the README just goes stale.
- Requirements corrected to what the project actually targets right
  now (Xcode 27+, macOS 27+) instead of stale Xcode 16/iOS 17 numbers.
- Privacy section expanded with a real inline summary, linking out to
  the wiki for the full Privacy Policy, Terms of Service, and Data
  Processing Statement rather than duplicating them as repo files.

 A native Apple ecosystem client for [Outline](https://github.com/outline/outline) — built for iOS, iPadOS, and macOS from a single SwiftUI codebase, aiming for full editing parity with Outline's web app, including realtime collaborative editing.
 
+> **Early alpha — macOS only for now.** Expect missing features and rough edges. iOS/iPadOS support is planned but not in the current build. See the [releases page](https://git.psmattas.com/psmattas/Outpost/releases) for changelogs, and [open an issue](https://git.psmattas.com/psmattas/Outpost/issues) if you hit anything.

 ## Why
 
 Outline's web app is great, but there's no native Apple client with full editing parity. This project connects to a self-hosted Outline instance over its REST API and realtime collaboration socket to provide a proper native experience across the Apple ecosystem.
 
-## Status
-
-Early development. See `CLAUDE.md` for the current architecture and phased build plan.
-
-- [ ] Phase 1 — Auth, browse, search, REST-only editing
-- [ ] Phase 2 — Realtime collaborative editing (Yjs/Hocuspocus)
-- [ ] Phase 3 — Offline cache, tables, embeds, comments, macOS polish
-
 ## Requirements
 
-- Xcode 16+
-- iOS 17+ / iPadOS 17+ / macOS 14+
+- Xcode 27+ (currently developed against an Xcode 27 beta — this is a hard minimum, not a suggestion)
+- macOS 27+. iOS/iPadOS support is planned but not in the current build (see the alpha note above) — same 27+ minimum will apply once it lands
 - A self-hosted (or hosted) Outline instance with API access
 
-> They will be updated. These are old requirements.
-
 ## Setup
 
 1. Clone the repo and open the `.xcodeproj` in Xcode.

+## Privacy
+
+Outpost collects nothing about you — no analytics, no telemetry, no crash reporting of its own, no age or demographic data, nothing. The only thing stored locally is your Outline server URL and API token (in the device Keychain) and, optionally, a local offline cache of what you've viewed. Everything else goes straight from your device to whatever Outline server you configure — there's no backend in between, and the developer has no access to your data or your server.
