[PATCH 0/3] Add configuration fragment support to kdevops

This series introduces Linux kernel-style configuration fragment support
to kdevops, enabling flexible configuration composition and better
maintainability.

* Import merge_config.sh from Linux kernel for fragment merging
* Update scripts/config with latest upstream fixes (v5.11 -> v6.15)
* Add practical VM configuration fragments for guest scaling

Benefits:
- Modular configuration: Compose complex configs from reusable fragments
- Better maintainability: Separate concerns (VM sizing, features, workflows)
- Flexible deployment: Mix and match fragments for different scenarios
- Upstream compatibility: Uses standard Linux kernel tooling

Usage example:

* Minimal development VM + diy enablement:
make dynamic_pcipassthrough_kconfig KDEVOPS_ENABLE_PCIE_KCONFIG=1
make defconfig-sysbench-mysql-atomic-tps-variability
./scripts/kconfig/merge_config.sh -n .config \
    ./defconfigs/configs/vm2g2c.config
    ./defconfigs/configs/diy.config \

This builds on the kconfig environment discussion [1] and provides an
alternative to the SAT solver solution.
