fix(network-proxy): add unix socket allow-all and update seatbelt rules (#11368 )

## Summary
Adds support for a Unix socket escape hatch so we can bypass socket
allowlisting when explicitly enabled.

## Description
* added a new flag, `network.dangerously_allow_all_unix_sockets` as an
explicit escape hatch
* In codex-network-proxy, enabling that flag now allows any absolute
Unix socket path from x-unix-socket instead of requiring each path to be
explicitly allowlisted. Relative paths are still rejected.
* updated the macOS seatbelt path in core so it enforces the same Unix
socket behavior:
  * allowlisted sockets generate explicit network* subpath rules
  * allow-all generates a broad network* (subpath "/") rule

Refactor network approvals to host/protocol/port scope (#12140 )

## Summary
Simplify network approvals by removing per-attempt proxy correlation and
moving to session-level approval dedupe keyed by (host, protocol, port).
Instead of encoding attempt IDs into proxy credentials/URLs, we now
treat approvals as a destination policy decision.

- Concurrent calls to the same destination share one approval prompt.
- Different destinations (or same host on different ports) get separate
prompts.
- Allow once approves the current queued request group only.
- Allow for session caches that (host, protocol, port) and auto-allows
future matching requests.
- Never policy continues to deny without prompting.

Example:
- 3 calls: 
  - a.com (line 443)
  - b.com (line 443)
  - a.com (line 443)
=> 2 prompts total (a, b), second a waits on the first decision.
- a.com:80 is treated separately from a.com line 443

## Testing
- `just fmt` (in `codex-rs`)
- `cargo test -p codex-core tools::network_approval::tests`
- `cargo test -p codex-core` (unit tests pass; existing
integration-suite failures remain in this environment)

feat(core): add structured network approval plumbing and policy decision model (#11672 )

### Description
#### Summary
Introduces the core plumbing required for structured network approvals

#### What changed
- Added structured network policy decision modeling in core.
- Added approval payload/context types needed for network approval
semantics.
- Wired shell/unified-exec runtime plumbing to consume structured
decisions.
- Updated related core error/event surfaces for structured handling.
- Updated protocol plumbing used by core approval flow.
- Included small CLI debug sandbox compatibility updates needed by this
layer.

#### Why
establishes the minimal backend foundation for network approvals without
yet changing high-level orchestration or TUI behavior.

#### Notes
- Behavior remains constrained by existing requirements/config gating.
- Follow-up PRs in the stack handle orchestration, UX, and app-server
integration.

feat(network-proxy): structured policy signaling and attempt correlation to core (#11662 )

## Summary
When network requests were blocked, downstream code often had to infer
ask vs deny from free-form response text. That was brittle and led to
incorrect approval behavior.
This PR fixes the proxy side so blocked decisions are structured and
request metadata survives reliably.

## Description
- Blocked proxy responses now carry consistent structured policy
decision data.
- Request attempt metadata is preserved across proxy env paths
(including ALL_PROXY flows).
- Header stripping was tightened so we still remove unsafe forwarding
headers, but keep metadata needed for policy handling.
- Block messages were clarified (for example, allowlist miss vs explicit
deny).
- Added unified violation log entries so policy failures can be
inspected in one place.
- Added/updated tests for these behaviors.

chore: change ConfigState so it no longer depends on a single config.toml file for reloading (#11262 )

chore: refactor network-proxy so that ConfigReloader is injectable behavior (#11114 )

Currently, `codex-network-proxy` depends on `codex-core`, but this
should be the other way around. As a first step, refactor out
`ConfigReloader`, which should make it easier to move
`codex-rs/network-proxy/src/state.rs` to `codex-core` in a subsequent
commit.

refactor(network-proxy): flatten network config under [network] (#10965 )

Summary:
- Rename config table from network_proxy to network.
- Flatten allowed_domains, denied_domains, allow_unix_sockets, and
allow_local_binding onto NetworkProxySettings.
- Update runtime, state constraints, tests, and README to the new config
shape.

chore: introduce *Args types for new() methods (#10009 )

Constructors with long param lists can be hard to reason about when a
number of the args are `None`, in practice. Introducing a struct to use
as the args type helps make things more self-documenting.

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`
