release: v0.1.0 .deb bundle

Bundle of all phases (P0-P5) plus the diagnostic fixes from the
end-to-end test session: ephemeral peer/metrics ports, no reqwest
connection pool, short-poll inbox, expanded sidecar path probe.

Smoke-tested by exchanging messages with a second mycelium node in
a Docker container against the public Threefold seed
tcp://188.40.132.242:9651 — bidirectional delivery confirmed.

Built on Debian 12 (bookworm), x86_64, glibc-targeted but the
embedded mycelium binary is musl static.

+# Releases
+
+Pre-built `.deb` of the mycellium-ui desktop client. Tested on Debian 12 (bookworm); should work on any apt-based distro shipping `libwebkit2gtk-4.1-0` (Ubuntu 24.04+, Debian 12+).
+
+## Install
+
+```bash
+sudo apt install ./mycellium-ui_0.1.0_amd64.deb
+```
+
+`apt install` with a local path resolves runtime deps (`policykit-1`, `libwebkit2gtk-4.1-0`, `libgtk-3-0`) automatically. Plain `dpkg -i` will fail if any of those are missing.
+
+## Verify
+
+```bash
+sha256sum -c SHA256SUMS
+```
+
+## What's inside
+
+| Path | Purpose |
+|---|---|
+| `/usr/bin/mycellium-ui` | GUI launcher |
+| `/usr/bin/mycelium` | Mycelium daemon (v0.6.1, runs as root via pkexec) |
+| `/usr/share/polkit-1/actions/tech.threefold.mycellium-ui.policy` | polkit action — auth cached per session (`auth_admin_keep`) |
+| `/usr/share/applications/Mycellium UI.desktop` | Menu entry |
+
+## Uninstall
+
+```bash
+sudo apt remove mycellium-ui
+```
