include <algorithm> in tbb/concurrent_queue.h - #280

CRAN's clang-trunk (clang 23) checks fail to install RcppParallel:

https://www.stats.ox.ac.uk/pub/bdr/clang23/RcppParallel.log

include/oneapi/tbb/concurrent_queue.h:275:63: error: no member named 'equal' in namespace 'std'
include/oneapi/tbb/concurrent_queue.h:669:49: error: no member named 'equal' in namespace 'std'

concurrent_queue.h uses std::equal in the operator== of both
concurrent_queue and concurrent_bounded_queue, but never includes
<algorithm> -- it relied on some other header dragging it in. libc++ trunk no
longer does, so compiling src/tbb/concurrent_bounded_queue.cpp fails and takes
the whole bundled oneTBB build down with it.

Adds the include, and records it in patches/ so it survives the next
tools/tbb/update-tbb.R run.

Notes

• Still unfixed upstream as of oneTBB master; the patch file says to drop this
  once it is.
• Swept every header under src/tbb for <algorithm>/<numeric> functions
  used without the include (std::max/std::min included) --
  concurrent_queue.h was the only one. concurrent_vector.h,
  concurrent_lru_cache.h, blocked_rangeNd.h and parallel_sort.h already
  include it explicitly.
• The remaining noise in that log (-Wunused-template,
  -Wunused-private-field) is from BDR's extra warning flags on upstream TBB
  code, not errors, and is left alone.

Verification

• git apply --check --reverse passes for all seven files in patches/.
• Syntax-checked the patched header at C++17 and C++20, plus the TU that
  actually failed on CRAN (src/tbb/src/tbb/concurrent_bounded_queue.cpp).
