• fix(exec-server): reject websocket requests with Origin headers (#24947)

  ## Why
  
  `codex exec-server` has a local WebSocket listener, but it did not apply
  the same browser-origin request handling as the `app-server` WebSocket
  transport. Requests that carry an `Origin` header should not be upgraded
  by this local transport, keeping both local WebSocket servers consistent
  and avoiding unexpected browser-initiated connections.
  
  ## What changed
  
  - Added an Axum middleware guard in
  `codex-rs/exec-server/src/server/transport.rs` that returns `403
  Forbidden` for requests carrying an `Origin` header.
  - Added an integration test in `codex-rs/exec-server/tests/websocket.rs`
  that covers rejection of an `Origin`-bearing WebSocket handshake.
  - Kept ordinary WebSocket clients unchanged: existing no-`Origin`
  initialization and process behavior remains covered by the crate tests.
  
  ## Validation
  
  - `just test -p codex-exec-server` test phase (`186 passed`; run outside
  the parent macOS sandbox so nested sandbox tests can execute)
  - `just clippy -p codex-exec-server`

• [exec-server] serve websocket listener via HTTP upgrade (#21963)

  ## Why
  
  `codex exec-server` should keep the existing public `ws://IP:PORT` URL
  shape while serving that websocket connection through an HTTP upgrade
  path internally. That keeps the client-facing configuration simple and
  allows the listener to work through intermediate HTTP-aware
  infrastructure.
  
  ## What changed
  
  - keep the emitted and configured exec-server URL as `ws://IP:PORT`
  - serve that websocket endpoint through Axum HTTP upgrade handling on
  `/`
  - expose `GET /readyz` from the same listener for readiness checks
  - route upgraded Axum websocket streams through the shared JSON-RPC
  connection machinery
  - initialize the rustls crypto provider before websocket client
  connections
  - preserve inbound binary websocket JSON-RPC parsing for compatibility
  with the prior transport behavior
  
  ## Verification
  
  - `cargo test -p codex-exec-server --test health --test process --test
  websocket --test initialize --test exec_process`

• feat: move exec-server ownership (#16344)

  This introduces session-scoped ownership for exec-server so ws
  disconnects no longer immediately kill running remote exec processes,
  and it prepares the protocol for reconnect-based resume.
  - add session_id / resume_session_id to the exec-server initialize
  handshake
    - move process ownership under a shared session registry
  - detach sessions on websocket disconnect and expire them after a TTL
  instead of killing processes immediately (we will resume based on this)
  - allow a new connection to resume an existing session and take over
  notifications/ownership
  - I use UUID to make them not predictable as we don't have auth for now
  - make detached-session expiry authoritative at resume time so teardown
  wins at the TTL boundary
  - reject long-poll process/read calls that get resumed out from under an
  older attachment

• Remove stdio transport from exec server (#15119)

  Summary
  - delete the deprecated stdio transport plumbing from the exec server
  stack
  - add a basic `exec_server()` harness plus test utilities to start a
  server, send requests, and await events
  - refresh exec-server dependencies, configs, and documentation to
  reflect the new flow
  
  Testing
  - Not run (not requested)
