[codex] Fix Windows sandbox build script lint (#26445)

## Why

The Windows ARM64 Cargo clippy job on `main` is failing because
workspace lints deny `clippy::expect_used`, and the
`codex-windows-sandbox` build script used `expect()` while reading
`CARGO_MANIFEST_DIR`.

## What changed

`codex-rs/windows-sandbox-rs/build.rs` now returns `Result<(), String>`
from `main()` and converts a missing `CARGO_MANIFEST_DIR` into an
explicit build-script error. The non-Windows early return and Windows
linker argument behavior are unchanged.

## Verification

- `just clippy -p codex-windows-sandbox -- -D warnings`
- `just test -p codex-windows-sandbox`
