The grigio/obs-cmd v1.0.0 release ships Linux builds as
obs-cmd-x64-linux.tar.gz; the old obs-cmd-v-x86_64-unknown-linux-musl.tar.gz
name no longer exists and curl was piping a 404 page into tar.
- Treat "timeout" and "interrupted system call" from ReadWithTimeout as
non-fatal — hidraw on Linux returns errors instead of (0, nil) for
both, causing false device-dead detection and reconnect loops
- Resolve icons_dir relative to the config file when the path is not
absolute, so the service finds icons regardless of working directory
- Installer now copies bundled icons to the config dir on first install
- install.sh: detects pacman/apt/dnf/zypper, installs Go and hidapi if
absent, prompts for dotfiles dir and creates ~/.config symlink
- Makefile: wire `make install` to install.sh
- README: document interactive install flow and dotfiles tree structure
