Pull request: build: pin diff.renames for deterministic patch export

`git format-patch` honors `diff.renames`, which defaults to `true` (rename detection only). If a user has `diff.renames=copies` configured at the system or global level, exported patches may encode new files as copies of similar existing files, causing spurious diffs when `e patches` is run against patches exported on other machines.

This pins `diff.renames=true` in the export script to match git's default and ensure consistent output regardless of local git configuration.

Pull request: Turbopack: Add line numbers to debug info in release-with-assertions profile

We use this profile in CI. Without debug symbols, we only get the line/column number of the panic, and we don't get line numbers in the whole backtrace: https://github.com/vercel/next.js/runs/64337217556#step:35:474

This can be difficult if the function in the backtrace that you care about is large.

This enables just enough debugging info in this profile for us to get line numbers in the backtrace.

Pull request: [v22.x] test: mark `test-strace-openat-openssl` as flaky

We have a test that started failing overnight on `ubi81_sharedlibs_openssl111fips_x64`:

- for v20.x-staging, passes on Feb 3 (https://ci.nodejs.org/job/node-test-commit-linux-containered/54624/nodes=ubi81_sharedlibs_openssl111fips_x64/), fails on Feb 4 (https://ci.nodejs.org/job/node-test-commit-linux-containered/54638/nodes=ubi81_sharedlibs_openssl111fips_x64/)
- for v22.x-staging, passes on Feb 3 (https://ci.nodejs.org/job/node-test-commit-linux-containered/54623/nodes=ubi81_sharedlibs_openssl111fips_x64/), fails on Feb 5 (https://ci.nodejs.org/job/node-test-commit-linux-containered/54646/nodes=ubi81_sharedlibs_openssl111fips_x64/)

It's unclear what's causing it, v24.x-staging does not seem to be affected. Let's mark the test as flaky so it doesn't block backports and release.

Pull request: Rewrite `query_ensure_result`.

It currently uses chaining which is concise but hard to read. There are up to four implicit matches occurring after the call to `execute_query_fn`.
- The first `map` on `Option<Erased<Result<T, ErrorGuaranteed>>>`.
- The second `map` on `Option<Result<T, ErrorGuaranteed>>`.
- The third `map` on `Result<T, ErrorGuaranteed>`.
- The `unwrap_or` on `Option<Result<(), ErrorGuaranteed>>`.

This commit rewrites it to use at most two matches.
- An explicit match on `Option<Erased<Result<T, ErrorGuaranteed>>>`.
- An explicit match on `Result<T, ErrorGuaranteed>`.

This is easier to read. It's also more efficient, though the code isn't hot enough for that to matter.
