Pull Request Overview

This PR introduces functionality to filter out unwanted SST files during a scan operation by adding a new "sst_min_sequence" field to the scan request, which is propagated through various components of the system. Key changes include:

• Adding the "sst_min_sequence" field and its documentation in the ScanRequest.
• Propagating and processing the field in QueryContext and within the scan logic in the engine.
• Updating tests to verify that the minimal SST sequence filtering works as expected.
• Bumping the greptime-proto dependency version in Cargo.toml.
