Stable Event Type IDs + +This PR introduces a stable `event_type_id` to all contract events, addressing the need for reliable event identification across contract upgrades. + +## Changes + +- Added `event_type_id: u32` to all event structs in `events.rs`. +- Updated all `publish_*` functions to initialize the `event_type_id`. + +## Reasoning + +By providing a stable identifier for each event, we can ensure that off-chain services can reliably track and process events, even if the event names or payload structures change in the future. This is a crucial step towards improving the long-term maintainability and interoperability of the contract. + +## Note + +The build environment on the agent's machine is experiencing issues with paths containing spaces, so the changes have not been fully verified by the agent. Manual verification is recommended. \ No newline at end of file
