[6/6] Fail exec client operations after disconnect (#18027 )

## Summary
- Reject new exec-server client operations once the transport has
disconnected.
- Convert pending RPC calls into closed errors instead of synthetic
server errors.
- Cover pending read and later write behavior after remote executor
disconnect.

## Verification
- `just fmt`
- `cargo check -p codex-exec-server`

Run exec-server fs operations through sandbox helper (#17294 )

## Summary
- run exec-server filesystem RPCs requiring sandboxing through a
`codex-fs` arg0 helper over stdin/stdout
- keep direct local filesystem execution for `DangerFullAccess` and
external sandbox policies
- remove the standalone exec-server binary path in favor of top-level
arg0 dispatch/runtime paths
- add sandbox escape regression coverage for local and remote filesystem
paths

## Validation
- `just fmt`
- `git diff --check`
- remote devbox: `cd codex-rs && bazel test --bes_backend=
--bes_results_url= //codex-rs/exec-server:all` (6/6 passed)

Add cached environment manager for exec server URL (#15785 )

Add environment manager that is a singleton and is created early in
app-server (before skill manager, before config loading).

Use an environment variable to point to a running exec server.

Refactor ExecServer filesystem split between local and remote (#15232 )

For each feature we have:
1. Trait exposed on environment
2. **Local Implementation** of the trait
3. Remote implementation that uses the client to proxy via network
4. Handler implementation that handles PRC requests and calls into
**Local Implementation**
