* fix(ghidra)!: search adjacent initialized memory blocks BREAKING CHANGE: Ghidra analysis snapshots from earlier byte-search policies are refused; reopen the target and create a new snapshot. Historical Evidence remains importable. * test(ghidra): supervise cross-block fixture process * docs(ghidra): clarify contiguous search range * test(ghidra): verify search metadata and cleanup --------- Co-authored-by: Cursor Agent <cursoragent@cursor.com>
