wmww/tawc v2 on GitHub

Fixes

Installs no longer fail at the Configure step on devices where the host shell had no writable temp dir (#13, #16 — thanks @pidjey for the diagnosis in #17).
pacman's "GPGME error: Invalid crypto engine" on Android 13 and older is fixed; gpg spawns were being silently killed (#14).
Go programs (fzf, micro, …) now run under tawcroot (#6).
LibreOffice starts: /proc/version, /proc/uptime and /proc/loadavg exist and /proc files can be stat'ed (#2).
Root inside the guest can write into read-only directories like real root, so mkdir /test under a 0555 / works (#12).
Firefox 156 tabs no longer crash.
GL apps no longer abort on devices whose vendor graphics driver links Android's libcrypto (libhybris #11).

Real mouse support: wheel, hover, right/middle buttons and cursor shapes (#10). Touch and stylus are unchanged.
The in-app terminal opens root's login shell, so chsh is honored.
Launcher shows SVG-only app icons, walks icon themes properly, and uses a neutral glyph for apps with no icon.

First release prepared for F-Droid's build server; the F-Droid listing is pending.
Upgrading over v1 keeps existing distro installs.
Known limitations: Android may kill or cut network to guest processes while TAWC is backgrounded; see the issue tracker.
