ci: switch CTO reviewer from Anthropic direct to OpenRouter

Reuses the OPENROUTER_API_KEY secret that already backs the other AI
plugins. Consolidates AI spend on one bill. Model: anthropic/claude-haiku-4.5.

-# Automated PR review powered by Claude + DeepSeek + Kimi (via OpenRouter)
-# plus Neurometric PR-Summarizer (a Qwen3-4B task-specialist SLM).
+# Automated PR review powered by Claude via OpenRouter.
 #
-# 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.
+# Reads the PR diff + repo conventions, calls OpenRouter for a structured review,
+# and posts APPROVE / REQUEST_CHANGES / COMMENT on the PR. Does NOT merge — merge
+# remains a human decision so the reviewer can't deploy to production alone.
 #
-# 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.
+# Requires a repo secret: OPENROUTER_API_KEY
+# (Routes to anthropic/claude-haiku-4.5 on OpenRouter; same bill as other AI plugins.)
 #
-# 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.
+# Cost profile (~$1/M input, $5/M output):
+#   ~$0.02 per PR review at typical diff sizes. Skipped for diffs >380KB.
