Fix process memory provider base address sync and live refresh

Browse Source 
Provider base address now stays in sync with tree base address when
changed via ChangeBase command, fixing reads from arbitrary memory
regions like KUSER_SHARED_DATA at 0x7FFE0000. ReadProcessMemory
handles partial reads gracefully. Snapshot extent uses tree-based
calculation instead of provider size to avoid oversized reads.
MCP source.switch gains pid parameter for programmatic process attach.
MCP server starts by default with logging and slow mode support.
