MATTER-5950

Description of Problem/Feature:
Extension PR to pick up project upgrades refactor for EVSE and Multi Sensor apps

Description of Fix/Solution:

• Bump submodule to latest matter_sdk release branch
• Update necessary slcp/slcw files
• Update README files

Testing Done:
CI (full run with smoke)
Local testing of overrides

---

Note

Medium Risk
Changes how EVSE apps are built and where application logic is customized (generated AppTask vs customer overrides), which can break existing forks that edited AppTask.cpp directly until they migrate to CustomerAppTask.

Overview
Aligns Matter EVSE Thread and Wi-Fi sample projects with the same CustomerAppTask / CRTP *Impl() extension model used by other Silicon Labs Matter examples.

Build / project wiring: Both .slcp files stop compiling the in-tree AppTask.cpp and including AppTask.h directly. They now pull in CustomerAppTask sources/headers, add EvseConfig.h as a config file, and rely on matter_evse.slcc to emit AppTask.h, AppTaskImpl.h, and AppTask.cpp into autogen/ via new template_file entries. The component SBOM license metadata is updated from MSLA to Apache 2.0.

Documentation: Thread and Wi-Fi READMEs gain an Extending Base App Implementation section (table of contents link included) that explains overriding Silicon Labs behavior through CustomerAppTask, how data-model callbacks moved from DataModelCallbacks.cpp into overridable AppTask hooks, sample header/cpp snippets, and pointers to autogen/AppTaskImpl.h and autogen/AppTask.cpp as the override reference.

PR Summary

Medium Risk
Example app build wiring and autogen templates change how customers override behavior; Jenkins smoke now runs three named pipelines only on main/release branches instead of always-on single smoke.

Overview
Aligns EVSE and multi-sensor Thread/Wi-Fi SLC projects with the CustomerAppTask customization model: projects no longer compile vendored AppTask.cpp / AppTask.h directly and instead pull CustomerAppTask from the shared Silicon Labs customer layer, while matter_evse and matter_multi_sensor_app components now declare AppTask / AppTaskImpl / AppTask.cpp as template_file entries so defaults land under autogen/. Multi-sensor builds drop explicit SensorManager, DataModelCallbacks, and app AppTask sources from the .slcp and add SensorConfig.h (and EvseConfig.h for EVSE) as config inputs.

Documentation for all four example READMEs gains an “Extending Base App Implementation” section covering CRTP *Impl() overrides, migration of data-model callbacks into AppTask, sample CustomerAppTask code, and (EVSE only) notes that energy-management delegates are still edited outside CRTP.

CI: the Jenkins Trigger SQA Smoke Pipeline stage no longer runs on every branch (removes a debug || true), and production smoke triggers change from a single smoke pipeline to smoke-thread, smoke-wifi, and smoke-cmp. matter_evse SBOM metadata switches license to Apache 2.0.
