Summary

This PR updates the ephemeral-validator dependency and configuration across the Bolt framework. The main changes involve updating the ephemeral-validator configuration template to use a new schema format required by the newer version of the tool.

The most significant change is in the ephemeral-validator.toml template file, where the configuration format has been modernized from underscore-separated keys to hyphenated keys (millis_per_slot → millis-per-slot, frequency_millis → frequency-millis). Additionally, the remote configuration has been restructured from a simple string value to a nested object (remote = "url" → remote.url = "url").

To support the dependency update, the sysinfo dependency in the root Cargo.toml has been pinned to an exact version (=0.36.1) instead of using a flexible constraint (^0). This ensures reproducible builds and prevents potential compatibility issues.

The .gitignore file has been updated to exclude new test ledger directories created by the updated ephemeral-validator, which now generates directories with the -magicblock suffix pattern. This change maintains consistency with existing ignore patterns for test artifacts.

These changes are part of a tooling update that doesn't affect core functionality but ensures the development environment uses the latest ephemeral-validator with its updated configuration schema.
