Deactivated the cross-chain message path (9b84db3)
Fixed a double claiming of delegation rewards: update_delegation, redelegation and claim_delegator_rewards transferred the accrued reward a second time on top of the transfer already performed by end_delegation_for (a67a8f2)
The matching extrinsics now verify that the job's assignment strategy matches the extrinsic used: propose_matching requires AssignmentStrategy::Single and propose_execution_matching requires AssignmentStrategy::Competing. Mismatches are rejected with the new WrongAssignmentStrategyInMatch error (7c60967)

Upgraded the pinned Polkadot SDK from polkadot-v1.18.5 to polkadot-stable2606. Includes the Rust toolchain bump to 1.97.0, the full API migration across runtimes and node, and regenerated weights (f6cd889)
Removed the pallet from the runtime (pallet index 45). The marketplace's cross-chain job hooks are gone with it, so no AssignJob / FinalizeJob messages are sent to proxy chains (f6cd889)
Stripped the pallet down to unlocking already converted tokens: the cross-chain token conversion (Acurast Canary to Acurast Mainnet) extrinsics have been disabled and related code removed (f6cd889)
