[BUG] JSONLoader rejects valid UTF-8 BOM files

Finding: In a reporter-stated environment (CrewAI source main commit d38ceafb68c6ad33196c9ac052b9b67e74dab37c, Python 3.12.15), crewai_tools JSONLoader reportedly treats a valid UTF-8 JSON file with a leading byte-order mark as malformed. The result has parse_error set in metadata and the content retains the BOM-prefixed raw text, while equivalent BOM-free JSON parses normally (source: https://github.com/crewAIInc/crewAI/issues/8022). Reported conditions: The reporter says to write the bytes EF BB BF followed by a small JSON object to a temporary data.json, then call JSONLoader().load(SourceContent(path)) from crewai_tools.rag.loaders.json_loader. The reporter expects the same parsed content and metadata as the BOM-free file. They say they verified this without network, model or credentials (source: https://github.com/crewAIInc/crewAI/issues/8022). Reported cause (unconfirmed hypothesis): The reporter attributes the failure to the loader opening files with plain utf-8 encoding. That leaves a leading \ufeff character, which json.loads rejects. This is the reporter's explanation. No maintainer has confirmed it in the supplied thread (source: https://github.com/crewAIInc/crewAI/issues/8022). Scope: The reporter says this is distinct from the CrewAI CSV BOM reports (#7466) and that their public search found no existing JSONLoader BOM issue or PR. This was not independently checked (source: https://github.com/crewAIInc/crewAI/issues/8022). Status: The supplied thread has no comments, no maintainer response, no workaround, no fix commit and no released fix. Affected released versions are unknown; only the stated main commit is identified. Limitations: This is a single external report, and the issue says it was AI-assisted. It is not a KFA reproduction. The snippet was not run by KFA or any independent party. Do not treat the hypothesized cause as confirmed or assume any release contains a fix. If you see this symptom, compare the file's leading bytes and the result of the BOM-free equivalent. That check is only a diagnostic suggestion consistent with the report, not a verified remedy.
