Use nesting instead of scoped css (#3939)

* fix: replace @scope by class nesting

* fix: remove nesting

Use huge pages for large buffers on Linux (#3937)

Buffers are allocated with plain new T[], which never calls
madvise(MADV_HUGEPAGE). With transparent_hugepage=madvise, the default on
many systems and common on HPC clusters where users cannot change it, Scipp
thus ran on 4 kByte pages while NumPy in the same process used huge pages,
since it madvises arrays of 4 MByte and more. libtbbmalloc_proxy and
TBB_MALLOC_USE_HUGE_PAGES do not help: tbbmalloc never calls madvise and
considers huge pages unavailable unless they are reserved explicitly or the
kernel setting is `always`.

Request huge pages for buffers of 4 MByte and more, matching NumPy's
threshold. Smaller ranges are left alone since the kernel rounds up to the
2 MByte huge page size. SCIPP_MADVISE_HUGEPAGE=0 disables the request.

See https://github.com/orgs/scipp/discussions/3936.

Update dev environment dependencies.

Remove pins for gmock and gtest (#3852)

* Remove pins for gmock and gtest

* trigger conda build

* bump gtest for wheel builds too

* dont fail fast

* fix segfaults

Remove min version pin for boost in CMake (#3836)

We don't need to add a strict lower pin here. Conda forge is still trying to rebuild packages for https://conda-forge.org/status/migration/?name=libboost188 and we don't need to rush here.

 Sync version requirements in CMakeLists with CPM (#3833)

* Sync version requirements in CMakeLists with CPM

* trigger builds

* sync conda build env

* remove pins, match conda-forge

* Update libboost-headers version requirement

* Specify libboost-headers version in meta.yaml

Changed libboost-headers dependency to a specific version.

* Update min deployment targets

* fix sdk version

* MACOSX_DEPLOYMENT_TARGET

* revert trigger
