Add macOS and Linux desktop shortcuts to install.sh (#4568)
* Add macOS and Linux desktop shortcuts to install.sh Adds create_studio_shortcuts() function that creates platform-native shortcuts after `unsloth studio setup` completes, mirroring the Windows shortcut behavior from PR #4558. Linux: .desktop file in ~/.local/share/applications/ and ~/Desktop/ macOS: .app bundle in ~/Applications/ with Info.plist, exec stub, and optional .icns icon built from unsloth-gem.png via sips+iconutil Both platforms share a Bash launcher script at ~/.local/share/unsloth/launch-studio.sh that provides: - Health check with service fingerprint verification - Port scanning (8888-8908) via ss/lsof - PID-file single-instance guard (no flock dependency) - Terminal spawning (macOS: Terminal.app; Linux: gnome-terminal etc.) - Browser open after health poll with 60s timeout WSL is skipped (no native desktop environment). * Fix 6 issues found by 10 parallel reviewers 1. [10/10] Health check now supports wget as fallback to curl via _http_get() helper, matching the installer's own download() pattern. Previously wget-only systems would time out on every launch. 2. [9/10] Exe path substitution now escapes sed metacharacters (&, \, |) and shell single-quotes before injection, preventing launcher corruption for paths like /opt/R&D/bin/unsloth. 3. [4/10] Linux .desktop Exec= field now quotes the launcher path, fixing launches from home directories containing spaces. 4. [3/10] macOS AppleScript command now escapes backslashes and double-quotes before interpolation into do script "...", fixing Terminal.app launch failures. 5. [3/10] Single-instance guard now uses atomic mkdir instead of racy check-then-write PID file, preventing duplicate concurrent launches on rapid double-click. 6. [1/10] Launcher now scans for a free port via _find_launch_port() instead of always hardcoding -p 8888, so Studio starts correctly when another service already occupies port 8888. Also fixed: `open` command on Linux (openvt) no longer incorrectly triggers the macOS browser-open path -- now gated on uname=Darwin. * Fix mktemp guard and exe path escaping from PR review comments Two real issues identified from automated review comments: 1. Guard mktemp -d failure in macOS icns generation. If mktemp -d returned empty, dirname would resolve to / and rm -rf would attempt to delete the root directory. Now checks that the temp dir was actually created before proceeding. 2. Replace sed-based exe path substitution with a conf file approach. The previous sed escaping broke paths containing apostrophes (e.g. /home/O'Connor/) because the '\'' escape introduced backslashes that were then double-escaped by the metacharacter pass. Now writes UNSLOTH_EXE to a separate studio.conf file that the launcher sources at runtime, eliminating all sed metacharacter and shell quoting interaction issues. This also addresses the sed -i.bak portability concern (now moot since sed is no longer used on the launcher file). * Fix unbound variable crash and per-user lock in launcher - Use ${UNSLOTH_EXE:-} so set -u does not crash before the friendly error message when studio.conf is missing or empty. - Append $(id -u) to the fallback lock path so each user gets their own lock directory when XDG_RUNTIME_DIR is unset. * Mark desktop shortcut as trusted for GNOME/Nautilus On modern GNOME desktops, chmod +x alone is not sufficient to make a .desktop file launchable by double-click on ~/Desktop. Nautilus requires the metadata::trusted attribute to be set via gio, otherwise it shows a warning dialog instead of launching the application.
