refactor(cost-map): remove openrouter rows, part 3 of 5

[devin-ai-integration]

Summary

Part 3 of 5 of removing the redundant litellm_provider: openrouter rows from the cost map (OpenRouter bills from usage.cost since #45640; see #45665 for why this is split into 5 stacked deletion-only PRs). Stacked on part 2

Deletes the third and fourth contiguous blocks, 139 rows starting at openrouter/minimax/minimax-m3 and including openrouter/typesafe/jev-1.13, from model_prices_and_context_window.json and litellm/model_prices_and_context_window_backup.json. The *_above_32k_tokens, *_above_128k_tokens and *_above_256k_tokens fields were only used by OpenRouter rows, so ci_cd/generate_model_prices_schema.py drops them from model_prices_and_context_window.schema.json here. No source or test changes

Check against the base branch:

python3 -c "import json,subprocess as s;o=json.loads(s.check_output(['git','show','origin/litellm_remove_openrouter_cost_map_2:model_prices_and_context_window.json']));n=json.load(open('model_prices_and_context_window.json'));r=set(o)-set(n);print(len(r),set(n)-set(o),all(o[k]['litellm_provider']=='openrouter' for k in r),all(o[k]==n[k] for k in n))"
# 139 set() True True

1.  Cheapest routing picks wrong models ▶

Summary

Removes 139 OpenRouter records from both model catalogs and drops ten now-unused price properties from the generated schema

• The cost maps no longer list these 139 OpenRouter models.

Cheapest routing picks wrong models

For a mixed-provider model group without custom prices, lowest-cost routing reads these records before sending a request. Deleting them makes both token rates default to 5.0, so the router ranks each deleted OpenRouter deployment at 10.0 and can choose a more expensive provider. usage.cost arrives after that choice and cannot fix it. Keep prices available for pre-response routing

•  Model information disappears model_prices_and_context_window.json:65196 ▶

  Deleting openrouter/minimax/minimax-m3 removes its limits and capability flags, not just prices. OpenRouter has no dynamic metadata lookup, and the existing generalizations do not cover MiniMax. get_model_info now raises ModelNotMappedError, while supports_function_calling returns false for a model previously marked as supporting tools. Keep this metadata available. The repository requires an opt-in for incompatible changes
