bug: timecopilot agent fails with large datasets

[noamanemobidata]

Initial Checklist

• I confirm that I'm using the latest version of TimeCopilot.
• I confirm that I've reviewed my issue at https://github.com/AzulGarza/timecopilot/issues before opening this one.

What happened?

The actual version does not support large time series datasets! maybe because all records are passed to the LLM ?

Relevant log output

raise ModelHTTPError(status_code=status_code, model_name=self.model_name, body=e.body) from e
pydantic_ai.exceptions.ModelHTTPError: status_code: 400, model_name: gpt-5-mini, body: {'message': 'Input tokens exceed the configured limit

Environment

Macos, python3.13, timecopilot==0.0.19

Interesting, for which dataset specifically you saw it failing?
