* feat(gemini): add gemini-3.1-flash-lite model cost map entries
Co-authored-by: Cursor <cursoragent@cursor.com>
* Update model_prices_and_context_window.json
* Update source URL for model pricing information
* Sync source URL for gemini-3.1-flash-lite in backup JSON
* fix(model_cost_map): add mistral/ministral-8b-2512 entry
Mistral rotated the 'mistral/mistral-tiny' alias to return
'ministral-8b-2512' as the response model, which is not in the cost map.
This caused test_completion_mistral_api and
test_completion_mistral_api_modified_input to fail in
completion_cost lookup. Add the entry mirroring the existing
openrouter/mistralai/ministral-8b-2512 pricing.
* test(cost_calculator): assert output_cost_per_reasoning_token for gemini-3.1-flash-lite
* fix(tests): backfill local backup entries into runtime model_cost
litellm.model_cost is loaded from LITELLM_MODEL_COST_MAP_URL (pinned to
main) at import time, so any pricing entries added to the in-tree backup
on this branch aren't visible at test runtime until they also land on
main. The Mistral cassette currently returns model=ministral-8b-2512
and the cost-calculator lookup in test_completion_mistral_api /
test_completion_mistral_api_modified_input fails despite the entry
existing in the local backup. Backfill missing backup entries into
litellm.model_cost in the local_testing conftest so these lookups
succeed against the cassette state the branch is being tested with.
* fix(tests): guard conftest backfill against empty local cost map
