v1.7.4 – YSCommands plugin & portable build improvements

What's new

YSCommands plugin

• Drive navigation: Ctrl+C → C:, Ctrl+D → D:, Ctrl+E → E:
• Directional copy/move: Ctrl+→/← copy, Alt+→/← move to right/left pane
• Dynamic action bar: compact 22px buttons; switches label set on Ctrl / Alt / Ctrl+Shift
• Windows dark title bar: all windows (including dialogs) use DWM dark mode automatically

Portable build

• build_portable.py now copies %APPDATA%/fman/Plugins/Third-party and User into the bundle
• portable_hook.py patches find_plugin_dirs at runtime so bundled plugins are discovered on any PC
• Added --hidden-import tinycss for FmanAlternativeColors

Bug fix

• FmanAlternativeColors: get_theme_filename() was using global current_theme instead of its name parameter, causing KeyError when switching themes
• unload_qss now uses .pop() to safely handle missing keys
