daymade a5f3a4bfbe fix(tunnel-doctor): add OrbStack transparent proxy + TUN conflict diagnosis
Real-world findings from debugging docker build failures on macOS with
OrbStack + Shadowrocket:

- Add docker pull vs docker build vs docker run proxy path distinction table
- Add 2G-1: --network host workaround for OrbStack transparent proxy broken by TUN
- Rewrite 2G-2: use host.internal (not 127.0.0.1) for OrbStack Docker proxy
- Add 2G-4: container healthcheck failure from lowercase http_proxy env var leak
- Add 3 new symptom entries to Step 1 diagnostic index
- Add smoking gun diagnosis: wget showing "127.0.0.1: Connection refused"
