Drop empty-name tools before forwarding to upstream#60

Codex's Responses API includes structured/typed tools (e.g. image_generation, web_search, file_search, computer_use) that have no `function.name` field because they are identified by `type` instead. The converter preserves the type info via Extensions but leaves Name empty, which causes upstream Anthropic-compatible endpoints like DeepSeek to reject the entire request with `tools[N].function.name: empty string`. These hosted tool types are OpenAI-specific and not executable on other providers anyway, so skip them in flattenToolsWithNamespace alongside the existing dedup pass.

Summary
image_generation,web_search,file_search,computer_use) that have nofunction.namefield — they are identified bytypeinstead.flattenToolsWithNamespacewithName == ""and Extensions like{"source_type":"image_generation"}./anthropic) then reject the request withInvalid 'tools[N].function.name': empty string, returning a 400 that Moon Bridge surfaces as 502 to Codex.Fix
Skip empty-name tools in
flattenToolsWithNamespace(alongside the existing dedup pass). These hosted tool types cannot run on non-OpenAI upstreams anyway, so dropping them is the correct semantic — not a hack.Test plan
