• fix: reject global wildcard network proxy domains (#13789)

  ## Summary
  - reject the global `*` domain pattern in proxy allow/deny lists and
  managed constraints introduced for testing earlier
  - keep exact hosts plus scoped wildcards like `*.example.com` and
  `**.example.com`
  - update docs and regression tests for the new invalid-config behavior

• feat: introducing a network sandbox proxy (#8442)

  This add a new crate, `codex-network-proxy`, a local network proxy
  service used by Codex to enforce fine-grained network policy (domain
  allow/deny) and to surface blocked network events for interactive
  approvals.
  
  - New crate: `codex-rs/network-proxy/` (`codex-network-proxy` binary +
  library)
  - Core capabilities:
    - HTTP proxy support (including CONNECT tunneling)
    - SOCKS5 proxy support (in the later PR)
  - policy evaluation (allowed/denied domain lists; denylist wins;
  wildcard support)
    - small admin API for polling/reload/mode changes
  - optional MITM support for HTTPS CONNECT to enforce “limited mode”
  method restrictions (later PR)
  
  Will follow up integration with codex in subsequent PRs.
  
  ## Testing
  
  - `cd codex-rs && cargo build -p codex-network-proxy`
  - `cd codex-rs && cargo run -p codex-network-proxy -- proxy`
