What changed

• Added deepseek/deepseek-v4.1-flash: $0.14/$0.28, 1,048,576 / 65,536, toolCalling. Flags mirror deepseek-chat (the gateway serves both from the same upstream in non-thinking mode, so no reasoning flag and no long reasoning timeout). Also in the picker (before deepseek-chat), with pins deepseek-v4.1-flash, deepseek-v4-1-flash and v4.1-flash. Bare deepseek still points at deepseek-chat.
• deepseek-chat / deepseek-reasoner renamed "(V4.1 Flash)" to match the gateway.
• Retired: the gateway now returns 400 for nvidia/deepseek-v4-flash and bare deepseek-v4-flash; blockrun removed the entry and its redirect on 2026-10-20. nvidia/deepseek-v4-flash, deepseek-v4-flash and v4-flash now resolve to the free default free/nemotron-3.5-lightning, like the v3.2/v4-pro ids. They never move to the paid V4.1 Flash. nvidia/deepseek-v4-pro already followed lightning; the gateway still redirects it to nemotron-3-super-120b (probed: HTTP 200).
• MODEL_ALIASES 292 → 295; brand-numbers.json updated to match. The blockrun-side bump is a separate PR.

No package.json change, no version bump.

Checks

• typecheck, lint, prettier: pass
• vitest: 1207 passed. The 5 failures were timeouts on a machine at load average ~145, and those files pass when rerun alone. test/upstream-proxy.test.ts fails to load (undici bind TypeError on Node 22.14); it fails the same way on origin/main without this change.

Changes: DeepSeek model update

Layer / File(s)	Summary
Catalog metadata src/models.ts	Updated the DeepSeek Chat and Reasoner labels and versions. Added the non-reasoning V4.1 Flash model with its pricing, limits, and tool-calling support. Retained the free V4 Flash entry for free classification.
Alias routing src/models.ts	Added explicit aliases for paid V4.1 Flash. Redirected free V4 Flash identifiers to the free default model while preserving other free DeepSeek mappings.
Validation and model listings src/models.test.ts, README.md, src/top-models.json, brand-numbers.json	Added tests for catalog details and alias resolution. Updated the README and top-model list, and increased the alias count from 292 to 295.
