Pull Request Overview

This PR implements post-upgrade changes for the 2025-May protocol upgrade by revising the chain state activation types and updating fork settings.

• In test/transaction_entry.cpp, the deprecated galois activation has been removed and replaced with a new parameter sequence including leibniz and cantor types.
• In src/settings.cpp and settings.hpp, fork flags and activation time constants are updated (with galois deactivated and cantor introduced) to align with the upcoming upgrade.
• In src/populate/populate_chain_state.cpp, the chain state constructors are updated to reflect the new upgrade logic by removing galois and adding cantor activation timing.

test/transaction_entry.cpp:45

• The ordering of activation type parameters has changed (galois removed and leibniz repositioned before introducing cantor). Consider verifying that the new parameter position aligns with the expected chain state constructor requirements.

kth::leibniz_t(0),

src/settings.cpp:105

• If the bch_cantor fork is not meant to be active post-upgrade, consider adding a clarifying comment indicating that it is intentionally disabled pending further updates.

// forks |= (bch_cantor     ? rule_fork::bch_cantor : 0);

src/populate/populate_chain_state.cpp:293

• The deprecation of galois_t in favor of a new activation type is clear; ensure that all consumers of the chain_state are updated to reflect this change to prevent any unintended issues at runtime.

// , galois_t(settings_.galois_activation_time)

include/kth/blockchain/settings.hpp:112

• Replace the placeholder 'xxxxxxxxxx' with a clearly defined constant or a more descriptive placeholder to improve code readability and maintainability.

// 2027-May-15 hard fork, defaults to xxxxxxxxxx: May 15, 2027 12:00:00 UTC protocol upgrade
