chore(dnp3): resync STORY-108 demo evidence + test comment to parse_errors [PC-014]

[PC-014] Resync STORY-108 demo evidence + test comment to parse_errors

Epic: fix-pc-013-014-015 — Post-merge consistency audit cleanup
Mode: maintenance
Convergence: N/A — docs/evidence/comment resync, no behavioral change

This PR resolves two post-merge consistency-audit findings (DRIFT-1 and DRIFT-2) from the
fix-pc-013-014-015 bundle. The fix(dnp3) rename of total_parse_errors → parse_errors
(landed in develop f5c002a, PR #313) left two artifacts out of sync: (1) the STORY-108 demo
evidence report and two .tape scripts still referenced the old key name, and (2) a test
comment in tests/dnp3_detection_tests.rs:1575 described the key as not-yet-renamed. This PR
re-records AC-010 and AC-011 demo GIFs/WEBMs with VHS, updates the two evidence-report lines,
and corrects the stale comment. No behavioral logic, test assertions, or public API surface
is changed.

Architecture Decision Record

ADR: Evidence Resync Only — No Behavioral Change

Context: PR #313 renamed the DNP3 analyzer output key total_parse_errors → parse_errors.
Demo evidence scripts and an explanatory test comment were authored before that rename was
complete and were not updated when the rename landed.

Decision: Re-record demos from .tape scripts updated with the correct key name; correct the
stale test comment in-place.

Rationale: Evidence must reflect current behavior. Stale comments referring to a rename that
is already complete cause confusion during future audits.

Alternatives Considered:

1. Leave evidence stale — rejected: violates post-merge audit policy (PC-014).
2. Re-generate entire STORY-108 demo suite — rejected: over-broad; only AC-010 and AC-011
   reference parse_errors directly.

Consequences:

• Evidence report and recordings accurately reflect the current parse_errors key.
• Test comment no longer describes future work that has already shipped.

Holdout Evaluation

N/A — evaluated at wave gate. No behavioral change; this PR contains no new features or
logic modifications.

---

Adversarial Review

N/A — evaluated at Phase 5. No new behavioral surface to adversarially review; this PR is
a documentation and evidence resync only.

Immediate rollback (< 2 min):

git revert a2c31ef8c560721df13ae3d71faabc66046703f1
git push origin develop

This reverts only the evidence resync commit; the underlying parse_errors rename (PR #313)
remains in place.

Audit Finding Closure

DRIFT-1 (evidence): evidence-report.md L26+L138 referenced "total_parse_errors"
  -> Fixed: updated to "parse_errors"; AC-010 and AC-011 re-recorded
DRIFT-2 (comment): dnp3_detection_tests.rs:1575 described rename as future work
  -> Fixed: comment updated to reflect rename completion (develop f5c002a)
