* fix(cli): escape codex args and stop aborting on exit in launch-codex
`launch-codex` spawns `codex.cmd` with `shell: true` on Windows, so Node joins
argv with plain spaces and no escaping (DEP0190). This mangles every Windows
invocation, not only the ones with a multi-word user argument, because the
injected `-c` provider flags carry quoted TOML values:
["-c","model_provider=omniroute", ...,
"model_providers.omniroute.base_url=http://localhost:20128/v1",
"fix","the","bug"]
cmd.exe strips the TOML quotes (`model_provider=omniroute` no longer parses as
a TOML string), splits multi-word arguments, and swallows everything after an
unquoted `&`. The same defect was fixed for `launch` in #8837; this ports it to
`launch-codex`, which that PR disclosed but left unfixed.
- extract the escaping into `bin/cli/utils/winShellArgs.mjs` and reuse it from
both launchers instead of keeping a private copy in `launch.mjs`
- quote the codex argv (provider flags + profile + pass-through args) on the
win32 shell path; argv is untouched off Windows, where no shell is involved
- replace `process.exit()` in the command action with `process.exitCode`: on any
non-zero child exit it aborted with the libuv `!(handle->flags &
UV_HANDLE_CLOSING)` assertion while the inherited stdio handles were closing
Test: `tests/unit/cli/launch-codex-windows-spawn-args.test.ts` pins the exact
encoding with golden strings (the cmd.exe round-trip is Windows-only and skips
on Linux CI, so without goldens CI would guard nothing) and round-trips the real
provider flags through a probe `.cmd` shim that forwards `%*`.

launch-codex spawns codex.cmd via shell on Windows (#6263 pattern). Added resolveCodexSpawn() helper + regression test (2/2), satisfying Hard Rule #18. Integrated into release/v3.8.46.
