viyatb-oai 457441bca9 Add constraint-aware standalone network proxy configuration (#57180)
## What changed

- Export `StaticNetworkProxyConfig` to parse and serialize network policy with constraints, and validate them before building proxy state.
- Add `--strict` and `from_slice_strict` for managed callers, requiring explicit `constraints` and rejecting unknown fields at every typed level. Default parsing permits top-level `metadata` and omitted constraints while still rejecting unknown policy fields.
- Match allowed Unix socket paths case-sensitively when validating constraints.
- Bound configuration file reads to the size limit plus one byte.

## Testing

Add coverage for constraint round trips, weakened policy rejection, exact socket path matching, parsing modes, and CLI flag selection. Exercise automatic MITM enablement through both parsers.

viyatb-oai e4dba902ab Support caller-provided MITM CAs in the network proxy (#47132)
## What changed

- Add optional `network.mitm_ca` configuration with `certificate_file` and
  `private_key_file` for trusted proxy configuration. Require MITM to be enabled
  and retain the generated CA when no external CA is configured.
- Validate absolute paths, regular files, file sizes, certificate/key matching,
  and Unix private-key permissions. Reject symlinks on Unix, private keys embedded
  in certificate files, and external private keys on non-Unix platforms.
- Store derived external-CA trust bundles in the proxy artifact directory,
  include only certificates, and skip inherited generated bundles to avoid
  retaining stale roots.
- Preserve MITM for external CAs when disabling credential brokerage. Reject
  external CA configuration for remote execution, even when the proxy is disabled,
  and reject unknown fields in `NetworkProxyConfig`.
- Default the upstream request version adapter to HTTP/1.1 and remove the request
  URI from upstream request failure context.

## Testing

Add regression coverage for external CA configuration, mismatched keys, embedded
private keys, non-Unix rejection, trust-bundle placement and contents, stale-root
exclusion, credential-broker toggling, and remote configuration rejection.

viyatb-oai 94e3c20906 Add a standalone network proxy binary with JSON configuration (#46573)
## Why

Allow the network policy proxy to run without a full Codex permissions profile.

## What changed

- Add `codex-network-proxy --config <PATH>` to load a standalone JSON file containing a `network` object and run the proxy independently of Codex.
- Require `network.enabled = true`, limit configuration size to 1 MiB, and reject unknown fields, including nested MITM hook fields, and trailing JSON values.
- Enable HTTPS MITM automatically for limited mode or configured `mitm_hooks`, while supporting explicit `mitm` configuration.
- Document the standalone configuration and invocation.

## Testing

Add tests for MITM defaults, dynamic policy keys, unknown fields, and trailing JSON values. Add a regression test that verifies `wait()` promptly returns an error when either the HTTP or SOCKS listener fails.
