feat: add automatic update system with GitHub Releases integration

[mkarim1378]

Implement a self-update mechanism that checks the GitHub Releases API on every startup, downloads the latest version if available, and applies it without touching user-owned files.

• Add src/updater.py:
  • check_update(): queries API with 10s timeout, compares semver tuples
  • apply_update(): downloads zipball, extracts to temp dir, copies files into project root while skipping protected paths (config.json, .venv, ca/, adblock_cache/, .git)
• Add --check-update flag to main.py: report only, exit 0
• Add --update flag to main.py: apply if available; exit 0 = already up to date, exit 1 = error, exit 2 = update applied
• Integrate into start.sh and start.bat:
  • Auto-check and apply on every startup before launching the proxy
  • Re-run pip install if exit code is 2 (new deps may be required)
  • Pass --skip-update to bypass the check entirely

I'm facing an issue where when Cloudflare captcha appears, my client can't solve or bypass it — it just keeps spinning and then reloads the captcha from the beginning.
Also, when I try to connect using LAN sharing with SOCKS5 or HTTP proxies on my phone, it doesn't work at all. I have set up the HTTP and SOCKS5 proxies correctly on my phone inside v2rayNG, and they even show ping successfully — but the actual connection still fails.
Checking logs when I open Telegram on my phone, I see this:
02:47:04 • INFO [Proxy ] Non-TLS traffic on 149.154.167.91:443 (likely Telegram MTProto / obfuscated protocol). This DC appears blocked; the client should rotate to another endpoint shortly.
what does that mean? and ... I'm not sure why the log says "Proxy" there — I think it should say "LAN" (or something similar) instead, but that's what I see.
This happens while Telegram Desktop itself works fine with the same setup.
Can anyone help me understand what's going on or how to fix it? Thanks!

P.S. I'm using the latest version I could download (around 17:00 Tehran time on May 2nd).
