Module block 

The --to-block block-identifier port .

Mirrors cli/pool.py::_resolve_to_block and its cli/aave.py twin exactly:

• a concrete integer is used as-is;
• a pure tag (latest, safe, …) with no offset resolves to None — the Rust core fetches the chain tip via eth_blockNumber itself;
• a tag with an offset (latest:-64, safe:128) or a concrete integer resolves to a concrete block number (the tag’s block + the offset).

Parsing is split from resolution so the semantics are unit-testable offline: parse_to_block is pure, resolve_to_block performs the one RPC read a tag+offset needs.

Enums

BlockTag

A block tag accepted by --to-block.

ToBlockSpec

A parsed --to-block value, before the tag’s block number is read.
