* fix(mcp): report target after failed open
* test(session): cover failed open receipt ownership
* test(session): verify restored target receipt
* test(mcp): retain target on snapshot mismatch
* test(mcp): retain oversized open failure receipts
* test(cli): avoid continuing session receipt in one-shot errors
* fix(mcp): report provider after failed switch
* test(ghidra): verify failed open preserves annotations
* test(mcp): join queued receipt request before cleanup
* test(session): assert open failure receipts in lifecycle suites
* test(session): keep open-failure receipt checks within function limits
