Adds an opt-in diagnostic that emits one tracing line per guest store overlapping any armed byte address, naming the writer (tid, pc, lr) plus old/new u32 lanes. Mirrors the --pc-probe / --branch-probe shape; pc/lr are stamped from worker_prologue via a thread-local Cell, so default runs (empty watch set) take a single is_empty() check on each write. Lockstep digest preserved (instructions=100000003 across reruns, sylpheed_n50m.json golden byte-identical). Diagnostic infra only; no functional change. Used to identify producers of dispatch-state writes for the audit-017 / audit-019 hunt.
