peptiderepo 000c21a9e8 feat(ci): add Neurometric PR-Summarizer as 4th QA voice (#9)
Neurometric markets a task-specialized PR-Summarizer SLM (Qwen3-4B +
specialist system prompt) on a free tier. Adding it as a 4th voice in
the existing A/B reviewer panel to see whether a specialized small
model catches things the 3 general-purpose voices miss.

The SLM does not honor OpenAI tool-calling, so it cannot return our
structured submit_review schema. Wired as a "prose voice":

- MODELS tuple gains a 6th provider_type field
  ("openrouter_tools" | "neurometric_prose")
- call_model() dispatches; new call_neurometric_prose() path hits
  api.neurometric.ai/v1 without tools, embeds raw markdown output,
  and infers verdict from keyword heuristic
- Render branch in PR comment marks the verdict as heuristic and
  notes tokens/cost are not tracked (free tier)
- Never the primary voice; heading still driven by Haiku

Also hardens the shared render path against models that omit the
optional 'summary' field (rev.get('summary') fallback).

Requires new repo secret NEUROMETRIC_API_KEY (already set on all four
peptiderepo repos). Voice self-skips with inline error if missing.

# Automated PR review powered by Claude + DeepSeek + Kimi (via OpenRouter)
# plus Neurometric PR-Summarizer (a Qwen3-4B task-specialist SLM).
#
# During the A/B window (until further notice), every PR gets reviewed by FOUR models
# in parallel. The PR comment shows each model's verdict side-by-side so we can compare
# quality/cost on real PRs before picking a permanent default.
#
# Neurometric is a "prose voice": it does not support OpenAI tool-calling, so its
# contribution is raw markdown + a heuristic verdict. It is never the primary voice.
#
# Does NOT merge. Does NOT post formal APPROVE/REQUEST_CHANGES reviews — always COMMENT
# (GITHUB_TOKEN can't formally approve PRs without repo-setting toggle).
#
# Requires repo secrets: OPENROUTER_API_KEY, NEUROMETRIC_API_KEY (optional; the
# Neurometric voice self-skips with an inline error note if the key is missing).
#
# Cost cap: tracked in Repository Variables (CTO_REVIEW_SPEND_CENTS, CTO_REVIEW_CAP_CENTS).
# Default cap is 1000 cents ($10/month). Auto-resets on the 1st of each month.

Your job:
1. Assess whether the change is safe to merge and deploy to production (peptiderepo.com on Hostinger WordPress).
2. Flag security issues, cost traps (paid AI API usage), performance regressions, missing input sanitization, missing output escaping, hardcoded secrets, broken migrations, or violations of the repo's CONVENTIONS.md.
3. Check that the PR follows the project's git workflow: branch naming (claude/<scope>-<date>), Agent-Session trailer in commits, PR description covers what/why/risk/test-plan.
4. Be concise and direct. No pleasantries. Call out concrete line-level issues when possible.
You MUST respond by calling the submit_review function. Do not write prose outside the tool call.
Verdict rubric:
- APPROVE: No blocking issues. Safe to merge.
- REQUEST_CHANGES: Blocking issues present. State them clearly.
- COMMENT: Non-blocking observations only, or change is outside your review capability.
