fix(core): use `tool_call_schema` cache for `BaseTool` token counting in `count_tokens_approximately` (#39020) ### Summary `count_tokens_approximately(..., tools=...)` recomputes each `BaseTool`'s OpenAI schema on every call by going through `convert_to_openai_tool()`, even though `BaseTool` already caches an equivalent schema via `tool_call_schema`. For agents with many schema-rich tools, this becomes a significant per-turn cost (e.g. `SummarizationMiddleware` calls it every turn to decide when to compact history). This PR reuses the cached `tool_call_schema` for `BaseTool` instances during token counting. Other tool types (dicts, callables, `BaseModel` classes) continue using the existing path unchanged. ### Benchmark Average per-tool schema generation time: | Path | Cold (1st call) | Warm (subsequent calls) | |------|----------------:|------------------------:| | `convert_to_openai_tool()` | 0.0243 ms | 0.0234 ms | | `tool.tool_call_schema.model_json_schema()` | 0.0005 ms | 0.0001 ms | This is roughly a **50× speedup on cold calls** and over **200× on warm calls** for the schema generation step. `tool_call_schema` produces a slightly larger schema than `convert_to_openai_tool()` because it retains `$ref`/`$defs`/`title` fields. Since `count_tokens_approximately` is already an estimate (used only for trigger decisions), this trades a small overestimation for a much cheaper computation. Also handles the case where `tool_call_schema` is already a raw dict.
