"""Hardened SearX-backed web tools (search, fetch, image search).

All results are passed through the deerflow.security pipeline:
- HTML cleaning (strip script/style/iframe/etc.)
- Unicode sanitizer (zero-width chars, control chars, PUA, tag chars)
- Content delimiter wrapping (semantic boundary for the LLM)

These tools are the ONLY web access surface in this hardened build.
The legacy community web providers (ddg_search, tavily, exa, firecrawl,
jina_ai, infoquest, image_search) are deliberately disabled — see
deerflow/community/_disabled_native.py.
