Crate sst_inspect 

SST file inspector binary for turbo-persistence databases.

This tool inspects SST files to report entry type statistics per family, useful for verifying that inline value optimization is being used.

Entry types:

• 0: Small value (stored in value block)
• 1: Blob reference
• 2: Deleted/tombstone
• 3: Medium value
• 8-255: Inline value where (type - 8) = value byte count
