feat: implement muse switch — focused branch switcher

Cleaner alternative to checkout for branch operations. Delegates to checkout's internal machinery; adds: -c (create), -C (force-create / reset existing branch to HEAD), 'switch -' (previous branch via .muse/PREV_BRANCH), --discard-changes, --detach, --merge, --autostash, --dry-run, --json. 37 TDD tests: flag parsing, PREV_BRANCH helpers, all switch modes, security, stress.
