Collapse related alerts into one incident, process-lineage first with a
time-window fallback. Each alert batch's flagged PIDs are walked up the
/proc PPid chain into a lineage set (excluding pid 0/1 so everything
doesn't correlate through init); batches whose lineage sets intersect —
sharing a process or a common ancestor like the web server or SSH
session — join the same incident. PID-less batches (FIM drift, package
tamper, hidden modules) fall back to the most recently active open
incident within incident_window.
snapshot.capture now computes lineage and records each snapshot into a
JSON incident index (incidents.json), writing incident_id into both the
report JSON (report level, so the per-alert schema is untouched) and the
text header. New commands:
incident list incidents newest-first, with signatures
incident show <id> summary + time-ordered snapshot timeline
incident export <id> JSON bundle: record + inlined snapshots
The lineage/assign cores are pure functions; record() serializes the
index under a lock (capture runs from sweep + eBPF threads) and is
best-effort so an index problem never loses a snapshot. 17 new tests
(lineage, assign, record, and an end-to-end capture→group→CLI path).
Config: incident_tracking / incident_window / incident_lineage_depth.
Docs + sample config updated; closes the last v0.8 roadmap item.
