Adds bloxbean/yaci-store as a long-running N2N consumer alongside oura,
pinned by content digest. Reuses p1-configs for genesis files; H2
in-memory backing store; 30s healthcheck warm-up.

Verified locally: yaci-store reaches relay tip in ~30s (slot=28,
block=2 hash match), survives a relay1 restart with a clean reconnect
(RestartCount=0), exits 143 on docker stop (JVM signal-exit, see
R-006).

Updates research.md R-006 and spec.md Assumptions to record the
SIGTERM-143 behaviour (not exit 0 as initially extrapolated).

Add a `--testnet-config-dir` flag that auto-discovers the 4 infrastructure
parameters (socket path, signing key, node config file, target nodes) from
a `cardano-testnet` output directory.  Discovered infrastructure always
overrides user-provided values; all other config fields must be supplied
by the user.
