* feat(studio): one timeline tool picker with select leftward and rightward The Selection and Razor buttons become one button showing the active tool, with a menu: Select (V), Split (B), Select leftward ([) and Select rightward (]). Leftward and rightward select every clip, on every track, that starts before or at/after the playhead. * test(studio): toolbar order and label follow the tool picker * fix(studio): select leftward and rightward use the live playhead and the usual selection resets * style(studio): keep playerStore's comment share at its base
