What's Changed

• Adds a new endpoint (get_block_headers) as specified in dfinity/interface-spec#298.
• Reduces the maximum number of instructions in heartbeats from 4B to 1B. This helps keep the finalization rate of the subnet smooth and improves response times.
• Adds a config for eager evaluation of fees, which is useful for local dev environments.
• Adds the candid interface to the metadata section.
• Improves serialization of unstable blocks when upgrading

This release is primarily focusing on the integration and enhancement of the watchdog canister.

Key additions are the inclusion of a watchdog canister with configurations for both mainnet and testnet, configurable explorers, and its verification in the Docker build process and the checks-pass workflow.

Changes include refactoring for end-to-end tests and improved debugging, while fixes address issues around HTTP requests and metrics handling.
