fixup(SR-173): correct cross-references SR-167 #167 / SR-168 #168

The Protocol-Shim TODOs and AGENTS.md brain-section referenced #173/#174 as
the placeholder issue numbers for SR-167/SR-168, but the canonical numbers
are:

  - SR-167 -> issue #167  (Post-Action Verifier Node)
  - SR-168 -> issue #168  (Triple-Channel Attestation)

#173 is actually SR-159 Path Doctrine. Fix all references in:
  - survey/observability/visual_debug.py  (Protocol docstrings + TODOs)
  - survey/runner_policy.py               (related-issues block)
  - survey-cli/AGENTS.md                  (SR-173 brain-section)

No runtime change. Tests still 12/12 green.

 PROTOCOL SHIMS FOR SR-167 / SR-168
 ==================================
-`VerificationResult` (from SR-167 / #173) and `AttestationResult` (from
-SR-168 / #174) are not yet merged on `main` at the time SR-173 was implemented.

+SR-168 / #168) are not yet merged on `main` at the time SR-173 was implemented.
 We declare `typing.Protocol`-based shims here so:
 
   - this module compiles + tests run today;
   - once SR-167/168 land, the *only* change is replacing the Protocol import
     with a `from survey.reliability.verifier import VerificationResult` in
     the type-checker's eyes -- no run-time changes.
