[ANNOUNCE] rteval-v3.11

rteval 3.11 Release Highlights:

Major New Features:

* cpuset support for cgroup v2 management - This is the biggest addition
  - New cpuset module and cpusetmanager for CPU isolation
  - --housekeeping option to reserve isolated CPUs
  - --cleanup-cpusets flag to remove leftover cpusets
  - Comprehensive test suite (732 lines of cpuset tests)

* Core sharing validation - New CPU topology awareness
  - Warns when measurement and load threads share CPU cores
  - --warn-non-isolated-core-sharing option
  - CoreSiblings class for topology queries

Critical Bug Fixes:

* Fix timerlat and cyclictest error handling to prevent hangs
* Fix timerlat module for rtla short option parsing bug

New Features:

* -L/--logging support added to both timerlat and cyclictest measurement modules

Code Quality & Testing:

* Major testing improvements - regression tests, reorganized unit tests, e2e test fixes
* New CpuList class with comprehensive unit tests for better CPU list handling

Documentation:

* Modernized documentation - updated man page (398 lines changed), new README-tests,
  added make uninstall target
