Title
spacetime publish panics in system_configuration when run from Codex tool context on macOS

Summary
Running spacetime publish from the Codex app tool context on macOS panics with Attempted to create a NULL object in system_configuration::dynamic_store::SCDynamicStoreBuilder::build, while the same command works fine in a regular terminal.

Environment

• OS: macOS
• Command context: Codex app tool execution
• Working directory: /Users/pziersch/code/spacetimedb-connector/my-spacetime-app
• SpacetimeDB CLI: installed locally (same binary used successfully in normal terminal)

Repro Steps

1. From Codex app tool context, run:

spacetime publish --project-path spacetimedb/ my-db-test

1. Observe panic.

Expected
Module publishes successfully (same as running in a normal terminal).

Actual
Panic with Attempted to create a NULL object.

Backtrace (top)

system_configuration::dynamic_store::SCDynamicStoreBuilder<T>::build
hyper_util::client::proxy::matcher::mac::with_system
reqwest::async_impl::client::ClientBuilder::build
spacetimedb_cli::subcommands::publish::exec
spacetimedb_cli::main

Notes

• Clearing proxy env vars (HTTP_PROXY, HTTPS_PROXY, NO_PROXY) did not help.
• Full backtrace available (included below if needed).
• Suggest investigating environment/entitlements differences or proxy detection in reqwest/system_configuration when run from tool context.
