docs(readme): finalize for 1.0.0 public launch

- Confident 1.0.0 framing: version badge + stable status callout; drop
  "early-stage / active development" and inaccurate "full-text" wording
- Add "What makes Backspace different" section leading with the verified
  wedge (per-stream media controls + federation + complete/polished)
- Fix two overclaims to match source: no unread divider (-> mark-as-unread),
  search is LIKE-based not full-text (-> "message search")
- Surface previously-omitted, source-verified voice/media features:
  per-user & per-stream volume, connection inspector, viewer detection,
  auto-ducking, measured tile badge, device/EC/AGC controls, selective
  subscription, browser push-to-talk
- Add Idle/DND + custom status, drag-drop/paste upload, avatar/banner crop

+## What makes Backspace different
+
+Self-hosted chat usually forces a trade-off: gaming-grade voice and video, *or* a
+polished Discord-style experience, *or* federation between independent servers —
+rarely all three, and rarely with the fine-grained media controls people expect.
+
+Backspace does all three at once:
+
+- **Voice & video with a real control surface.** Not just "it has screen share":
+  choose resolution, frame rate, codec (VP9 or hardware H.264), and bitrate; set
+  independent 0–200% volume for every person *and* every screen-share; RNNoise
+  noise suppression; a live connection inspector (bitrate, codec, ping, packet
+  loss, jitter); and a per-tile badge showing each stream's measured
+  resolution/frame-rate. Screen sharing goes up to 4K/120fps within admin-set
+  bounds.
+- **Federation, not a walled garden.** Run your own instance and peer it with
+  others: cross-instance friends, DMs, calls, and presence — each server
+  independently owned, requests HMAC-authenticated.
+- **A complete, polished platform — not a demo.** Role-based permissions with
+  per-category and per-channel overrides, friends and group DMs, inline playable
+  media, moderation with audit trails, search, a desktop app, and an installable
+  mobile PWA — all in the warm, calm "Aether Drift" interface.
+
+You own the server, the data, and the network it federates into.
