fix(plugins): install plugin packages from a .zip (#896)

Root cause: Install Plugin from Disk only opened a folder picker and the host could only copy folders, so a zipped plugin could not be installed. The picker now accepts a .zip or a package's plugin.toml, and the host's install_from_path unpacks a zip to a temporary folder and runs it through the existing install_from_dir validation. The package may sit at the archive root or in its only folder (archiver metadata such as __MACOSX is ignored). Archives with unsafe paths or symbolic links, more than 10,000 entries or over 1 GB unpacked are refused, and a zip without plugin.toml (e.g. an IntelliJ plugin) gets a clear error.

Fixes #892
