Restricted address read demotion

Bundles containing any transaction that reads the builder wallet (0xe89c42BC188c993273Ab34231e12ae60c73042E4) or the system address (0xFffffffFfFFFffffffFfFfFFfFFFfFFfFe) — including BALANCE, STATICCALL, or SLOAD — will receive a significantly lower inclusion priority.

Both addresses should be treated as write-only.
