Relax autoUpdater typing to avoid TS overload errors with linux shim

[garvvgognaa]

Fixes the issue where Hyper.app froze at startup behind corporate proxies that require authentication.

Issue

When Hyper starts, it performs network calls for:

Auto-updater

Plugin installer

In corporate environments with authenticated proxies, these requests hang indefinitely, causing the app to freeze during startup.

Cause

The app made blocking network requests without:

Detecting offline/proxy-blocked environments

Setting proper timeouts

Handling TypeScript typing issues around IPC + AutoUpdater

Solution

Added an isOnline() check (3s timeout) to detect network availability and skip update/plugin flows when offline.

Added a 10s timeout to Linux auto-updater fetch.

Fixed TypeScript type errors in:

IPC handlers

AutoUpdater typings

Added better logging when network calls fail or are skipped.

Result

Hyper no longer freezes in proxy-restricted environments.

App skips updates/plugins gracefully when offline.

Network issues now produce clear warnings instead of hangs.
