Subject: [PATCH] test(e2e): unified A2A round-trip parity harness across all 4
 runtimes

Adds two scripts:

  scripts/test-all-runtimes-a2a-e2e.sh
    Provisions one workspace per runtime (claude-code, hermes, codex,
    openclaw), sets provider keys, waits online, sends two A2A messages
    per workspace. First message validates round-trip; second message
    validates session continuity. Cleans up via trap on EXIT.

  scripts/test-hermes-plugin-e2e.sh
    Hermes-only variant focused on the plugin /a2a/inbound path.
    Proof-point: session continuity between turns (the plugin path's
    deliverable; old chat-completions path lost context per turn).

Both honor SKIP_<runtime> env vars for incremental testing and tolerate
the SaaS edge WAF Origin header requirement (per
reference_saas_waf_origin_header.md).

Run:
  PLATFORM=https://demo-tenant.staging.moleculesai.app \\
      ./scripts/test-all-runtimes-a2a-e2e.sh

+# E2E test: A2A round-trip parity across all four runtimes.
+#
+# Validates that for each of {claude-code, hermes, codex, openclaw}:
+#   1. A workspace can be provisioned + brought online
+#   2. The adapter responds to A2A message/send
+#   3. The reply contains expected content (echo of the prompt)
+#   4. A SECOND message preserves session state where the runtime
+#      supports it (currently: hermes via plugin path)
+#
+# Targets a SaaS tenant subdomain. Provisions workspaces in the calling
+# tenant, runs the round-trip, deletes them on success.
