ci(review): drop panel to Haiku-only per QA A/B decision 2026-06-12

A/B analysis across 13 PRs (convo/cto/threads/2026-06-qa-ab-review/02-analyst-findings.md):
- DeepSeek: high false-positive rate (absint()="code exec", PLUGIN_DIR="dir traversal")
- Kimi: ~60% model failure rate, 1 unique-real finding in 13 PRs
- Neurometric: summarizer only, 0 unique-real findings, unreliable heuristic verdict label
- Haiku: 0 failures, lowest noise, equivalent real-signal catch vs 4-voice panel

Removes DeepSeek, Kimi, and Neurometric voices. Haiku is now sole reviewer.
Also removes NEUROMETRIC_API_KEY env var (no longer needed).
No plugin version bump -- CI-only change (precedent: prautoblogger #150).

-# Changelog
-
-All notable changes to Peptide News Plugin are documented here.
-Format: [Keep a Changelog](https://keepachangelog.com/en/1.0.0/).
-Versioning: [Semantic Versioning](https://semver.org/).
-
-## [2.5.0] — 2026-06-16
-
-### Changed
-- **CI standardization (estate wave 2):** Replace per-repo CI jobs in
-  `ci.yml` with a thin caller of `peptiderepo/peptide-e2e/.github/workflows/ci.yml@main`
-  (`tests: stubs`, `has_js: true`). Adds `workflow_call` trigger so `deploy.yml`
-  gate remains valid.
-- Extract `security-audit` job from `ci.yml` into standalone
-  `.github/workflows/security-audit.yml` (kept as-is, unique to this repo).
-- `deploy.yml`: elevate permissions to `contents: write` so the nested
-  phpcbf commit-back step in the reusable workflow receives the correct token scope.
-- `composer.json`: pin `test` script to `vendor/bin/phpunit --configuration phpunit.xml.dist`
-  for explicit path resolution in CI; pin `lint` / `lint:fix` to `vendor/bin/`.
-- `phpunit.xml.dist`: add XSD reference for PHPUnit 9.6; drop deprecated
-  `convertErrorsToExceptions`, `convertNoticesToExceptions`, `convertWarningsToExceptions`
-  attributes.
-
-### Notes
-- `rollback.yml` and `cto-review.yml` and `main-push-audit.yml` unchanged — unique / estate-separate.
-- No functional code changes in this commit.
-
-## Prior history

-Versions prior to 2.5.0 were not tracked in a CHANGELOG. See git log for details.
