…r/http sinks Make socket data easy to analyze with common tools. Adds, all reusing the existing envelope-marshaller + destination patterns: Formats (envelope marshallers, marshallers_text.go): - jsonl — one raw JSON record per line (NDJSON / ClickHouse JSONEachRow) - csv/tsv — reflection-generated columns (all 122 XtcpFlatRecord fields by default, or a -columns subset), humanized: IPs as dotted-quad/v6, TCP state and congestion as names, timestamp as RFC3339 (humanize.go, flat_record_row.go). Header written once per stream. Destinations (stdlib, no build tag): - tcp:host:port — reliable streaming to Vector/Logstash/Fluentd/nc (fills the UDP-only gap) - file:/path — append to a file (reuses writerDest, 0600) - stderr — one-liner over writerDest - http(s)://... — POST each batch; Content-Type derived from the marshaller Framing: marshallers now own their trailing newline and writerDest/tcp/http write bytes verbatim, so text formats are newline-delimited on every sink while protobufList stays a clean length-delimited stream. Config: new -columns flag → csv_columns proto field; marshal_to min_len 4→3 so "csv"/"tsv" validate (regen-protos updated all language bindings). Tests cover the humanizer (incl. the IPv4-in-16-byte-slot regression), reflection columns + selection, jsonl/csv/tsv output, and tcp/file/stderr/http sinks (net.Listen / httptest). Verified end-to-end in a container: csv/jsonl of real host sockets to stdout with humanized addresses/states. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

Makes xtcp2 socket data easy to analyze with everyday tools (R/pandas/DuckDB/jq/Vector). Reuses the existing envelope-marshaller and destination patterns.

Marshallers now own their trailing newline;
writerDest/tcp/httpwrite bytes verbatim. Text formats are newline-delimited on every sink, whileprotobufListstays a clean length-delimited stream. (Adjusts the\nbehavior introduced in #35.)Config
