fix(ai): redact local file paths from AI payloads

[chubes4]

Summary

• redact file_info.file_path from AI-visible data_packets JSON in AIStep
• keep runtime/original packets unchanged so fetch, vision, and publish flows still use internal file paths normally
• add focused tests proving local file paths are removed from model payloads

Why

Fetch handlers can attach file_info with local/internal file paths so downstream runtime steps can access files. That is valid internal pipeline state.

The problem is that AIStep was serializing the full data_packets array directly into the model prompt. That exposed local paths like dm-files, temp paths, or legacy server paths to the model, which can then be copied into generated post content.

This is not Reddit-specific. Reddit made the bug obvious on wire posts, but the exposure path is generic:

FetchHandler -> DataPacket(file_info) -> AIStep JSON serialization

So the safest fix is at the AI serialization boundary in core.
