Add a read-only list_registry MCP tool for querying a remote Windows host's registry. An empty path returns the five root keys; a path such as HKEY_LOCAL_MACHINE plus subkeys returns that key's immediate subkeys and values (name, type, and formatted data). Client side: enumerate with KEY_READ instead of KEY_ALL_ACCESS and map the full value-type set (REG_SZ, REG_DWORD, REG_BINARY, REG_EXPAND_SZ, REG_MULTI_SZ, REG_QWORD, REG_NONE) so unknown types are no longer mis-reported as REG_SZ. The registry manager now always sends both the TOKEN_REG_PATH and TOKEN_REG_KEY packets (an empty packet when a part is empty), making the two-packet reply deterministic for the server. Server side: add the three-phase flow (COMMAND_REGEDIT, COMMAND_REG_FIND, then PATH plus KEY) with per-host pending state, parse the fixed-width wire format with bounds checks, format value data for JSON, and guard registry paths against exceeding MAX_PATH to protect the client stack.
