Reason: This proposal upgrades the Registry canister. Build is successful, hashes match, commits match descriptions and the reasoning behind the changes is sound. Commits are reviewed below.
[49d659c29d]
Updates dependencies on ic-cdk (canister development kit) to version 0.18.6 throughout the repo, along with other version updates including those listed in the commit notes. Implements ic-cdk-executor in order to allow interaction from earlier versions of ic-cdk, and ic_cdk::futures for managing asynchronous canister tasks, along with further changes as outlined in the description.
[2c1572e940]
Removes the old routing table logic from several code sections. Removes is_routing_table_single_entry_obsolete flag and several calls to make_routing_table_record_key. Drops the equality check between rt_from_shards and rt_from_routing_table_record from get_routing_table.

Refactors the registry canister by ceasing updates to the obsolete single-entry routing table, removing related feature flags, invariant checks, and tests while simplifying mutation and retrieval logic to solely use sharded formats.
