Add SAL-BOF for remote registry operations

Remote Registry Manipulation

Overview

This PR adds a comprehensive suite of Beacon Object Files (BOFs) to the extension-kit, providing native registry interaction capabilities: find, query, write, and delete.

These tools are designed for stealthy, in-memory execution, avoiding the heavy EDR telemetry generated by spawning reg.exe or using high-level API wrappers.

Key Features

The following actions are now supported as modular BOFs:

• reg_query: Enumerate subkeys and values (supports REG_SZ, REG_DWORD, REG_BINARY, etc.).
• reg_query_recursive: Recursively enumerate all subkeys and values under a specified key.
• reg_find: Recursively search for specific keys or values within a hive.
• reg_write: Create new keys or modify existing values.
• reg_delete: Remove specific values or entire key trees.
