claude_uninstall/gemini_uninstall/codebuddy_uninstall accepted project_dir
but, with the default project=False, still deleted the user-global skill
tree, so a library/test caller passing a project_dir nuked ~/.claude et al
(the API trap behind #2168). They now take remove_user_skill and treat a
passed project_dir as authoritative; uninstall_all opts in explicitly to
preserve 'graphify uninstall' behavior. Also fixes a live CLI bug where
'uninstall --project' deleted the global codebuddy skill.

Several test files call install/uninstall functions that operate on the
real user home (~/.claude, ~/.gemini, ~/.codebuddy, ~/.copilot), so
running the suite deleted/overwrote the developer's actual config. An
autouse conftest fixture now points HOME/USERPROFILE/LOCALAPPDATA at a
throwaway dir and clears CLAUDE_CONFIG_DIR/XDG_CONFIG_HOME for every
test. Supersedes the per-file sandbox proposed in #2057 (thanks
@erlandl4g for surfacing it).
