Michael Bolin af215eb390 refactor: decouple shell-escalation from codex-core (#12638)
## Why

After removing `exec-server`, the next step is to wire a new shell tool
to `codex-rs/shell-escalation` directly.

That is blocked while `codex-shell-escalation` depends on `codex-core`,
because the new integration would require `codex-core` to depend on
`codex-shell-escalation` and create a dependency cycle.

This change ports the reusable pieces from the earlier prep work, but
drops the old compatibility shim because `exec-server`/MCP support is
already gone.

## What Changed

### Decouple `shell-escalation` from `codex-core`

- Introduce a crate-local `SandboxState` in `shell-escalation`
- Introduce a `ShellCommandExecutor` trait so callers provide process
execution/sandbox integration
- Update `EscalateServer::exec(...)` and `run_escalate_server(...)` to
use the injected executor
- Remove the direct `codex_core::exec::process_exec_tool_call(...)` call
from `shell-escalation`
- Remove the `codex-core` dependency from `codex-shell-escalation`

### Restore reusable policy adapter exports

- Re-enable `unix::core_shell_escalation`
- Export `ShellActionProvider` and `ShellPolicyFactory` from
`shell-escalation`
- Keep the crate root API simple (no `legacy_api` compatibility layer)

### Port socket fixes from the earlier prep commit

- Use `socket2::Socket::pair_raw(...)` for AF_UNIX socketpairs and
restore `CLOEXEC` explicitly on both endpoints
- Keep `CLOEXEC` cleared only on the single datagram client FD that is
intentionally passed across `exec`
- Clean up `tokio::AsyncFd::try_io(...)` error handling in the socket
helpers

## Verification

- `cargo shear`
- `cargo clippy -p codex-shell-escalation --tests`
- `cargo test -p codex-shell-escalation`
