terra: package rishot, a quickshell screenshot/annotation overlay

Not in nixpkgs — upstream ships a shell launcher + QML tree with no build
step, driven entirely by `qs -p <dir>`. Packaged as a stdenvNoCC derivation
that wraps the launcher with RISHOT_CONFIG_DIR (sidesteps its argv0-relative
self-lookup, which wrapProgram breaks) and its runtime deps on PATH.
