GET_SECURITY_INFO (0x14) is ROM-only; stub returns 0xC0. Cache the response during detectChip() and return it from readSecurityInfo(). When stub is loaded and no cached info is available, return UnsupportedCommandError with guidance to use ChipAuto. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

Summary
GetSecurityInfo()for querying device security/fuse statusFlashMD5(offset, size)for verifying flash region contents by hashEraseRegion(previously would fail with a confusing error when called without stub)Use case
These public methods enable tools built on espflasher to verify flash contents and query device security state without reimplementing the protocol layer.
Test plan
go test -v ./pkg/espflasher/...— all tests passTestFlashMD5RequiresStubverifies stub guardTestGetSecurityInfoverifies response parsinggolangci-lint run ./pkg/espflasher/...— no new issues
