test(profiler/behave_shell): Phase 6 smoke harness + live-decky runbook

Two-half deliverable per BEHAVE-INTEGRATION.md §587-594:

* scripts/behave_shell/replay_calibration.py — Python helper that
  drives the production handler against one asciinema shard, mints
  a temp SQLite repo + an Attacker per session, captures bus
  emissions in-process. Exits non-zero on zero-observation sessions.

* scripts/behave_shell/smoke.sh — bash entry that replays all five
  2026-05-02 calibration shards (HUMAN / YOU-sim / LW-sim /
  CLAUDE-FF / CLAUDE-CL). Auto-activates .311 venv, forces
  DECNET_DB_TYPE=sqlite, prints per-class summary. Suitable for CI.

* scripts/behave_shell/README.md — runbook covering both halves.
  Pins the manual live-decky procedure (one SSH session per class
  against a deployed smoke-decky, expected dominant primitives table,
  SQL verification query, AttackerDetail panel check, pass criteria).

* BEHAVE-INTEGRATION.md — Phase 6 completion log appended with
  current corpus results table (15 sessions, 424 observations across
  the five classes) and a note that the v0 tag (drop -pre) is gated
  on the manual live-decky round-trip and lands as a separate
  commit.

Live-decky run is intentionally NOT scripted — the integration doc
calls for manual SSH sessions per class so an operator confirms the
bus / collector / disk-reach plumbing under real PTY conditions.

+### Usage: scripts/behave_shell/smoke.sh [BEHAVE_CALIBRATION_DIR]
+#
+# BEHAVE-INTEGRATION Phase 6 — offline replay smoke test.
+#
+# Runs the production handler
+# (`decnet.profiler.behave_shell._handler.handle_session_ended`) against
+# each of the five 2026-05-02 calibration shards, asserts every session
+# in every shard produces ≥ 1 observation, and prints a per-class
+# summary.
+#
+# This is the **offline** half of Phase 6. The **live-decky** half is
+# documented in `scripts/behave_shell/README.md` — that one needs a
+# real PTY round-trip and stays manual.
+#
+# Argument:
+#   $1   Optional path to the directory holding
+#        sessions-2026-05-02-*.jsonl. Defaults to
+#        ../BEHAVE/prototype_extractors/shell relative to this repo.
+#
+# Exits 0 on full pass, 1 on any class regression, 2 on bad input.
