718c4637a8 feat(mcp): allow native MCP OAuth support for cursor (#28327)
* feat(mcp): allow native MCP OAuth redirect URIs (cursor://)

Discoverable OAuth /authorize rejected cursor:// callbacks because
validate_trusted_redirect_uri only accepted http/https. Add an
allowlisted native path with a built-in Cursor default and optional
MCP_TRUSTED_NATIVE_REDIRECT_URIS env for other clients.

* fix(mcp): address Greptile native redirect URI review

Lowercase paths in normalizer so env allowlist entries match case-
insensitively. Tighten wildcard prefix matching to reject sibling
paths (e.g. callback-2) unless the prefix ends with /.

* fix(mcp): reject query params on native OAuth redirect URIs

Greptile: normalization stripped query strings before allowlist compare,
so cursor://.../callback?injected=... could pass validation. Reject any
native redirect_uri with a query component (same as fragments).

* 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.

* fix(mcp): lowercase default native redirect URIs

Make _parse_trusted_native_redirect_uris apply the same lowercasing
to built-in defaults as it does to env-var entries.

* fix(tests): backfill local model_cost into remote-fetched map

litellm.model_cost is loaded at import time from the URL pinned to main,
so pricing entries that exist only in this branch (e.g.
mistral/ministral-8b-2512, freshly added because Mistral now returns this
id from mistral-tiny) are absent at test time and completion_cost lookups
raise. Backfill the in-tree backup so cassette-driven cost calculations
resolve against the entries that ship with the branch under test.

Fixes the local_testing_part1 failures on test_completion_mistral_api and
test_completion_mistral_api_modified_input.
