Remove Windows sandbox resource stamping

[iceweasel-oai]

Why

The codex-windows-sandbox crate was embedding Windows resource metadata through a package-level build.rs. Because that package also exposes the codex_windows_sandbox library, downstream binaries that link the library could inherit FileDescription / ProductName values of codex-windows-sandbox.

That made ordinary Codex binaries, including the long-lived codex.exe app-server sidecar, appear as codex-windows-sandbox in Windows UI surfaces such as Task Manager / file properties.

We do not rely on this metadata enough to justify a larger bin-only resource split, so this removes the resource stamping entirely.

What changed

• Removed the windows-sandbox-rs build script that invoked winres.
• Removed the setup manifest that was only consumed by that build script.
• Removed the winres build dependency and corresponding Cargo.lock / MODULE.bazel.lock entries.
• Removed the now-unused Bazel build-script data.

Verification

• cargo build -p codex-windows-sandbox --bins
• cargo build -p codex-cli --bin codex
• bazel mod deps --lockfile_mode=update via Bazelisk, with local remote-cache-disabling flags because bazel is not installed on PATH here
• bazel mod deps --lockfile_mode=error via Bazelisk, with the same local flags
• Verified rebuilt codex.exe, codex-command-runner.exe, and codex-windows-sandbox-setup.exe now have blank FileDescription / ProductName fields.
• cargo test -p codex-windows-sandbox still fails on two legacy Windows sandbox tests with CreateRestrictedToken failed: 87 and the follow-on poisoned test lock; 85 passed, 2 ignored.
