Core packages: config validation, network renderers, root helper, auth, SQLite store, capture engine

Capture engine streams dumpcap pcapng into verbatim, hashed segments with
per-segment tshark summaries; display filters, PDML dissection with verified
byte ranges, export and import. Tests run in a Debian trixie container.
