## Summary
- restore the `#16634` `lzma-sys` / `xz` Bazel wiring that was reverted
from `main`
- re-enable direct Bazel linkage to `@xz//:lzma` with the `lzma-sys`
build script disabled
- restore the matching `MODULE.bazel.lock` entries
## Why
`origin/main` currently builds `//codex-rs/cli:cli` on a devbox, but
`bazel run //codex-rs/cli:codex -- --version` fails at link time on the
same remote path. Restoring `#16634` fixes that repro.
## Validation
- on `origin/main`: `bazel build --bes_backend= --bes_results_url=
//codex-rs/cli:cli` passed
- on `origin/main`: `bazel run --bes_backend= --bes_results_url=
//codex-rs/cli:codex -- --version` failed on `dev`
- after this patch on the same `dev` mirror: `bazel run --bes_backend=
--bes_results_url= //codex-rs/cli:codex -- --version` passed and printed
`codex 0.0.0`
