✓Diagnose and fix conflicts between Tailscale and proxy/VPN tools (Shadowrocket, Clash, Surge) on macOS. Covers two conflict types - route hijacking (proxy TUN overrides Tailscale routes) and HTTP proxy env var interception (http_proxy/NO_PROXY misconfiguration). Use when Tailscale ping works but SSH/HTTP times out, when curl to Tailscale IPs returns empty/timeout, or when setting up Tailscale SSH to WSL instances.

Diagnose and fix conflicts when Tailscale coexists with proxy/VPN tools on macOS, with specific guidance for SSH access to WSL instances.
Key distinction: SSH does NOT use httpproxy/NOPROXY env vars, but curl/wget/Python requests/Node.js fetch do. If SSH works but HTTP doesn't, it's almost always a proxy env var issue, not a route issue.
Check if proxy env vars are intercepting Tailscale HTTP traffic:
