Subject: [PATCH] fix(backend): resolve circular import for block exclusion
 constants
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Move EXCLUDED_BLOCK_TYPES and EXCLUDED_BLOCK_IDS to backend/data/block.py
to break the circular import chain:
embeddings.py → content_handlers.py → find_block.py → hybrid_search.py → embeddings.py

The constants now live alongside the BlockType enum they reference,
and all consumers import from the single source of truth.
