Zijie Tian a50b4c2ac2 ♻️ refactor: move select_blocks from policy to attention layer ...

Move block selection logic from compute_chunked_prefill/decode methods
to attention.py caller. This improves separation of concerns:

- attention.py now calls select_blocks() before compute_chunked_*()
- Policy methods receive pre-selected blocks via selected_blocks parameter
- Enables sparse policies to implement custom block selection without
  modifying the compute path

Changes:
- policy.py: Add selected_blocks parameter to abstract methods
- full_policy.py: Remove internal select_blocks calls, use passed blocks
- xattn_bsa.py: Sync signatures for prefill/decode methods
- attention.py: Add select_blocks calls before policy delegation
