[recipes] Fix typed-edge-classifier model routing for OpenRouter

[hadolphs]

Problem

recipes/typed-edge-classifier/classify-edges.mjs ships with Anthropic's canonical model names as defaults (claude-haiku-4-5-20251001 for the filter, claude-opus-4-7 for classify). When the provider is OpenRouter — the recipe's recommended provider — resolveModel() only prepends anthropic/, producing slugs like anthropic/claude-haiku-4-5-20251001 that don't exist on OpenRouter. OpenRouter exposes these models under dotted slugs (anthropic/claude-haiku-4.5, anthropic/claude-opus-4.7).

The result is that every Haiku-filter and Opus-classify call fails, so a default run writes nothing:

[classify-edges] status counts: { filter_error: 3 }
[classify-edges] estimated spend: $0.0000 of $0.50 cap

Fix

Add an explicit OPENROUTER_MODEL_MAP and consult it in resolveModel() before falling back to the bare anthropic/ prefix, mapping the names OB1 ships as defaults to their OpenRouter slugs.

• Anthropic-direct path unchanged — guarded by provider !== "openrouter".
• Cost cap unaffected — estimateCost() / assertPricingKnown() are always called with the raw, pre-resolve names, which remain keys in PRICING. No PRICING changes and no default-model changes.
• Docstring + README updated to describe mapping rather than prefixing.

Verification

With OpenRouter configured, the same run now classifies and writes edges:

[classify-edges] status counts: { inserted: 2, filter_rejected: 1 }
[classify-edges] estimated spend: $0.0541 of $1.00 cap
  [ok] inserted   conf=0.85  ... -[evolved_into]-> ...
  [ok] inserted   conf=0.75  ... -[related_to]-> ...

Rows confirmed present in public.thought_edges.
