jay77721 fe02c9b95f feat(go-models): unify OpenAI-compatible token usage extraction (#17634)
## Summary
Relate to #17284 .

- Add `usage_parser.go`: `extractOpenAIUsage` /
`extractOpenAIStreamUsage`
  with multi-field fallback (`prompt_tokens`/`input_tokens`,
  `completion_tokens`/`output_tokens`).
- Add `parser_config.go`: `ParserConfig` struct and
`OpenAIParserConfig`.
- Add `response_handler.go`: `HandleNonStreamingResponse` /
  `HandleStreamingResponse` as single entry points that extract usage,
  populate `chatConfig.UsageResult`, and emit a `StreamUsage` log.
- Extend `base_model.go` with `doRequest` / `doStreamRequest`.
- Migrate `deepseek` driver to shared handlers, cutting ~100 lines.
- Add `usage_parser_test.go`.
