build(deps): bump the bazel-packages group across 1 directory with 2 updates

[dependabot]

Bumps the bazel-packages group with 2 updates in the / directory: abseil-cpp and rules_cc.

Updates abseil-cpp from 20250814.1 to 20260107.1

Release notes

Sourced from abseil-cpp's releases.

Abseil LTS branch, January 2026, Patch 1

Abseil LTS 20260107.1

What's New

• absl::StringResizeAndOverwrite(): A new function in absl/strings/resize_and_overwrite.h that acts as a polyfill for C++23's std::basic_string::resize_and_overwrite. This allows for efficient resizing and in-place initialization of strings, avoiding the overhead of default initialization, which is particularly useful when working with C-style APIs that write directly to a buffer. See abseil/abseil-cpp#1136 for performance notes.
• absl::chunked_queue: A new container in absl/container/chunked_queue.h optimized for use as a FIFO (First-In, First-Out) queue.
• absl::linked_hash_map and absl::linked_hash_set: New hash containers that maintain iteration order matching the insertion order. These are available in absl/container/linked_hash_map.h and absl/container/linked_hash_set.h.
• absl::down_cast: Added to absl/base/casts.h. This function provides a safer way to perform downcasts in a polymorphic type hierarchy. In debug builds (or when hardened asserts are enabled), it uses dynamic_cast to verify the validity of the cast and terminates the program if the cast is invalid. In optimized builds, it uses static_cast for performance.

Breaking Changes

• Mutex Deprecations: Legacy Mutex methods and MutexLock pointer constructors have been marked as deprecated. Users should migrate to the recommended APIs.
• The polyfill type absl::string_view is now an alias for std::string_view in all builds. (abseil/abseil-cpp@9ebd93a)

Abseil LTS branch, August 2025, Patch 2

Abseil LTS 20250814.2

What's New:

• absl::Mutex now contains lower-case method names like lock() and shared_lock() to align with standard C++ mutex methods. This allows absl::Mutex to be used with std::scoped_lock and friends. The old names are still present but may be removed in a future release.
• The RAII Mutex-locker types like absl::MutexLock, absl::ReaderMutexLock, and friends now accept references to absl::Mutex. The pointer-accepting constructors are now deprecated, and may be removed in a future release.

Breaking Changes:

• Nullability template types, which were deprecated in the May 2025 release, have been removed.
• absl::string_view(nullptr), which is undefined behavior according to the C++ standard, now triggers an assert failure. Note that unless you changed absl/base/options.h, absl::string_view is an alias for std::string_view, so by default you will be inheriting the behavior of your standard library instead of using the Abseil implementation.
