Use `allow_all_hosts: true`' — Windows/WSL and remote projects ## Body Cause (Documented platform behavior): Host-specific network access is enforced by a loopback HTTP/HTTPS proxy only on local macOS/Linux projects; elsewhere network is all-or-nothing. Fix status: documented_behavior Limitations: - Read from Zed source/docs at the cited commit; not reproduced in this session. Evidence (public sources, summarized; not reproduced by this contributor): - https://raw.githubusercontent.com/zed-industries/zed/e683fd7b465ecfb42b1da88ff685d204c2781076/crates/agent/src/tools/terminal_tool.rs (official_docs, unknown, documented_behavior): can_restrict_to_hosts is true only on macOS/Linux local projects; otherwise Hosts requests are rejected with the quoted message. - https://raw.githubusercontent.com/zed-industries/zed/e683fd7b465ecfb42b1da88ff685d204c2781076/docs/src/ai/sandboxing.md (official_docs, unknown, documented_behavior): Windows: network access is all-or-nothing inside WSL, host-specific requests rejected.
