M5 ship infrastructure: icon, version, release script, README

- scripts/make-icon.py: generates a 1024x1024 source.png — dark
  rounded square + 2x2 tile grid with one active-blue tile and one
  broadcast-orange tile (matches the in-app accent colors).
  Regenerated all desktop icon sizes via 'pnpm tauri icon';
  pruned iOS/Android/UWP outputs.
- Version bump 0.0.1 -> 0.1.0 across package.json, Cargo.toml,
  tauri.conf.json. First real release.
- scripts/release.sh: takes vX.Y.Z, sanity-checks (clean tree,
  on main, in sync, tag matches package.json, installer exists,
  tag not already present), tags + pushes, uploads NSIS .exe to
  Forgejo via tea releases create --asset.
- README rewritten: Install section pointing at Forgejo releases,
  Using-it cheatsheet for all M2-M4 features (splits, broadcast,
  palette, etc.), Develop/Test/Release triplet for the WSL<->Windows
  workflow, icon regen instructions.

+#   1. You've bumped the version in package.json, src-tauri/Cargo.toml and
+#      src-tauri/tauri.conf.json and committed + pushed to origin/main.
+#   2. You've run `pnpm tauri build` on the Windows host so the installer
+#      exists at src-tauri/target/release/bundle/nsis/*.exe.
+#   3. `tea login list` shows the `rdx4` login is active.
+#
+# Usage:
+#   scripts/release.sh v0.1.0
