…ofiles - Add /proc/mounts fallback for raid0 path discovery in MySqlServerConfiguration and PostgreSQLServerConfiguration. After StripeDisks creates an LVM volume, lshw no longer reports the logical volume, causing 'Expected disks not found'. The fallback reads /proc/mounts to find the raid0 mount point. - Search all disks (not just filtered) for raid0 access paths in both MySQL and PostgreSQL server configuration components. - Remove unsupported CreateTables and DistributeDatabase dependency steps from PostgreSQL Sysbench TPCC and OLTP profiles. - Tune HammerDB TPCC WarehouseCount to LogicalCoreCount * 10 and TPCH ScaleFactor to 1 for faster validation runs. - Fix HammerDBExecutor async method missing await warning. - Add copilot-instructions.md for repository development guidance.

Summary
Fixes raid0 disk detection failures in MySQL and PostgreSQL server configuration components, and updates database workload profiles for improved validation.
Key Changes
Bug Fix: Disk detection after LVM striping
After
StripeDiskscreates an LVM striped volume from NVMe disks,lshwno longer reports the logical volume device. This causedMySqlServerConfigurationandPostgreSQLServerConfigurationto fail with Expected disks not found.Fix: Added a
/proc/mountsfallback that reads the mount table to find the raid0 mount point when lshw-based disk discovery fails. Also changed both components to search all disks (not just filtered disks) for raid0 access paths.Profile Updates
