refactor(global-cli): drop redundant clippy allow attributes

[shulaoda]

Problem

crates/vite_global_cli/src/shim/dispatch.rs had six function-level clippy #[allow(...)] attributes (on get_npm_global_prefix, check_npm_global_install_result, dedup_missing_bins, remove_npm_global_uninstall_links, read_npm_package_json, collect_bin_names_from_npm), all suppressing clippy::disallowed_types and/or clippy::disallowed_macros.

But main.rs already suppresses those lints for the whole crate:

#![allow(
    clippy::allow_attributes,
    clippy::disallowed_macros,
    clippy::disallowed_methods,
    clippy::disallowed_types,
    clippy::print_stderr,
    clippy::print_stdout
)]

A crate-level inner #![allow(...)] propagates to all descendant modules (dispatch.rs is one), so the per-fn attributes are dead. They lingered because clippy::allow_attributes — the lint that would flag a redundant #[allow] — is itself crate-allowed.
