With 'javascript: {}', moon v2 never adds an InstallDependencies action
to the graph, so fresh clones fail with 'vite: command not found' when
running any web/api task (#846). The javascript toolchain drives
installs and must be told bun is the package manager.
Also drop 'bun.installDependencies: true' (defaults to true, and was
inert without packageManager set) and stale comments.
Fixes#846
