feat!: replace got with native fetch as default downloader

[MarshallOfSound]

Summary

This is a proposed breaking change to reduce the dependency footprint of @electron/get by replacing the got HTTP client with Node's built-in fetch API.

Motivation

got is a heavyweight dependency with its own transitive dependency tree. Since @electron/get requires Node 22.12+, native fetch is guaranteed to be available and is sufficient for our use case of streaming file downloads.

Dependency changes

Dependency	Before	After
got	^14.4.5 (dependency)	❌ removed
global-agent	^3.0.0 (optional)	❌ removed
undici	—	^7.24.4 (optional, proxy support only)

Preserved behavior

• getProgressCallback receives a Progress object with transferred, total, and percent (same shape as got's progress events)
• Progress bar appears after 30 seconds (configurable via quiet or ELECTRON_GET_NO_PROGRESS)
• 404 errors throw HTTPError with message format Response code 404 (Not Found) for ${url}
• Parent directories are auto-created before download
• ELECTRON_GET_USE_PROXY still auto-initializes proxy support

New exports

• FetchDownloader — the new default downloader class
• FetchDownloaderOptions — options type extending RequestInit
• HTTPError — error class (previously re-exported from got)
• Progress — progress interface (previously re-exported from got)

---

BREAKING CHANGE: The default downloader now uses the built-in Fetch API instead of the got package. The GotDownloader and GotDownloaderOptions exports have been removed; use FetchDownloader and FetchDownloaderOptions instead. Download options now accept RequestInit options instead of got options. The initializeProxy() function now uses undici's EnvHttpProxyAgent instead of global-agent, reading HTTP_PROXY/HTTPS_PROXY/NO_PROXY environment variables directly (GLOBAL_AGENT_* prefixed variables are no longer supported).
