fix(hermes): wire all three contracts to reachability helper

The helper was correct but dead code - nothing called it. This commit:
1. Makes the helper runnable standalone: scripts/hermes-reachability-check.sh <host> <pattern> <path>
2. Wires all THREE contracts to it:
   - hermes-key-enforcement.prose.md
   - hermes-config-template.prose.md
   - hermes-agent-baseline.prose.md
3. Each contract now explicitly instructs to run the helper and interpret the three outcomes
4. States that the bug this replaces was deriving reachability from the remote grep's exit code

Files changed (4):
- scripts/hermes-reachability-check.sh (standalone mode added)
- hermes-key-enforcement.prose.md (reachability section added)
- hermes-config-template.prose.md (reachability section added)
- hermes-agent-baseline.prose.md (reachability section added)

 # Hermes Agent Baseline — Canonical Good State
 
+## Reachability Detection
+
+Before checking agent baseline, verify the host is reachable and can be audited. Use the shared reachability helper from the clone root:
+
+```bash
+# Run on each host to check reachability (Tanko, Mumuni, Koonimo, Koby)
+scripts/hermes-reachability-check.sh <host> "api_key:" "/root/.hermes/config.yaml"
+# Example: scripts/hermes-reachability-check.sh 192.168.68.122 "api_key:" "/root/.hermes/config.yaml"
+
+# Expected outcomes:
+# - UNREACHABLE: SSH connection failed (host is down)
+# - VIOLATION: SSH succeeded and found matches (report the finding)
+# - COMPLIANT: SSH succeeded and found no matches (no api_key in config)
+#
+# NOTE: The bug this replaces was deriving reachability from the remote grep's exit code.
+# The correct pattern: remote side always succeeds (grep ...; true), so ssh status = connection only.
