Fix pre-existing clang-format violations in linalg_internal_interface.cpp

[IvanaGyro]

Summary

• Reflow the Outer_ii and cuOuter_ii assignment expressions in src/backend/linalg_internal_interface.cpp (lines 228-229 and 723-724) to match clang-format-14 output, the version pinned by .github/workflows/clang-format-check.yml.
• Both expressions previously broke the line right after =, leaving a line over the 100-column limit; clang-format-14 instead breaks inside the std::vector<...>( argument list.
• No semantic change — confirmed with git diff --ignore-all-space, which shows no content differences once line-wrap position is ignored.

Context

These two violations are pre-existing on master. git blame traces them to commit bb2e1b29 ("removed using namespace std; from all src files; added missing std:: prefix"), part of PR #952 ("Remove namespace std", merged into master): adding the std:: prefix to vector<std::vector<Outerfunc_oii>>(...) pushed both lines past the formatter's wrap point, and the line break was never re-run through clang-format-14 before merging.

Test plan

• Verified with clang-format-14 -style=file -output-replacements-xml that the file now has zero replacements
• Re-ran the same check across every .cpp/.h/.hpp file under src/ and include/ to confirm no other formatting violations are introduced or remain
• Confirmed the diff is whitespace-only via git diff --ignore-all-space

Code Review

This pull request reformats the initialization of Outer_ii and cuOuter_ii in src/backend/linalg_internal_interface.cpp to improve line wrapping. There are no review comments, so I have no feedback to provide.
