subhobhai943andClaude Opus 4.8 f6e4511047 feat(net,gui): real internet access -- redirects, HTTPS guard, netcheck, and a live ONLINE indicator
The stack could already reach the real internet once the UDP-checksum and
scheduler fixes landed; this makes it work on real-world URLs and gives the
desktop a first-class "is the internet up?" answer.

HTTP client
  - Follows 3xx redirects (Location header, absolute or relative) up to five
    hops, so a bare host that 301s to a path or a canonical host resolves to
    actual content. Verified: `webget google.com/` follows the 301 to
    www.google.com and returns its HTTP 200 homepage.
  - Refuses https:// targets -- at the initial URL and on redirect -- with a
    clear message instead of speaking plaintext to port 443 and timing out.
  - Split the URL parser out so both the initial request and redirect targets
    go through the same path; added a case-insensitive header finder.

netcheck (CLI)
  One command that walks the whole chain -- link, address, gateway ping, DNS,
  and a real HTTP fetch -- and reports each PASS/FAIL, ending in ONLINE or
  DEGRADED. The one-shot answer to "is the internet working?".

Network Monitor (GUI)
  A live Internet: ONLINE/OFFLINE badge with the resolved IP, HTTP status and
  latency. It auto-probes once on open and re-checks on the Check button, all
  through the async HTTP worker so the window never blocks.

Verified against the real internet through QEMU's NAT: DNS resolved
example.com to a live Cloudflare address; `netcheck` passed all five layers
(Internet: ONLINE); the GUI badge showed "ONLINE 104.20.23.154 HTTP 200 240
ms"; redirect following and the HTTPS refusal both behaved. Builds clean on
x86_64, aarch64 and armv8i.

Known limit: no TLS, so HTTPS URLs are reported rather than fetched -- plain
HTTP only.
