rebuild_host: wipe-and-replace for full host re-profiles. Deletes all chunks for a hostname then bulk-ingests fresh sections. Supports confirm: false for dry-run preview. update_section: surgical in-place update with fuzzy section matching (case-insensitive substring, then vector similarity fallback). Preserves metadata, replaces text, re-embeds. Returns existing section list on no match. Addresses duplicate chunk problem caused by inconsistent section naming across profiling runs.
