feat(global-cli): add vp implode command to completely uninstall vite-plus (#761)

Implements a self-uninstall command that:

- Removes ~/.vite-plus/ directory
- Cleans shell profiles (.zshenv, .zshrc, .bashrc, .bash_profile,
.profile, config.fish) by removing Vite+ sourcing lines
- On Windows, removes .vite-plus\\bin from User PATH and handles
locked binary via deferred cmd.exe deletion
- Requires typing "uninstall" to confirm (or --yes/-y to skip)

Adds CI verification in test-standalone-install.yml for all platforms
(Unix + Windows) that tests implode followed by reinstall.

closes VP-236
