The threading cluster (#99429) branched before the auth cluster (#99427)
added auth_tag to _exec_buzz's signature; merging both left two
fake_exec doubles in test_buzz_thread_topology.py without the kwarg,
red on main. Sibling-test blast radius, no behavior change.
Real adapter imports with synthetic NIP-10 relay events; covers the composed
cluster behavior end to end: in-thread triggers anchor replies to the thread
root (never nesting), top-level triggers still open exactly one thread,
reply_in_thread/reply_to_mode opt-outs post flat on send/send_image/
standalone cron send, progress thread resolution honors the opt-out, and
buzz no longer inherits verbose _GLOBAL_DEFAULTS (#95841). Sabotage-checked:
the display-tier tests fail against origin/main's display_config.py.
