feat(harfanglab): map the fields the alert and threat payloads actually carry (v1.4.0)

Replayed a real get_alerts and a real get_threats response through the
bundled mappers to see what came out.

get_alerts: a sigma alert matching a Windows event log carries the whole
record under `eventlog`, and none of it was mapped. On a Defender 1116
detection that left the malware, the file, the acting user and the
detecting product invisible — the incident indexed a hostname and
nothing else. The event data uses the provider's own field names, spaces
included, so the new entries quote them with JSONata backticks, and
Defender's "file:_" path prefix is stripped. Also added the agent IP
(placed before details_connection.SourceIp so a network alert's own
source still wins), the DNS domain, device type, agent version and
groups, the tenant, the alert subtype and threat type, the string
severity and the event time.

get_threats: `level` had no entry at all, so a threat's severity never
reached the OCSF document even though field_mappings derived the
incident's 1-5 from it. Added it, the event time, and the top agent's
reachability — whether the endpoint is online decides what response is
possible, and it was excluded without a reason.

Both trailers now record why each remaining field is left out, and the
event log's own SYSTEM writer and FQDN spelling are called out: indexing
them would create a junk user entity and a second spelling of one host.

+changelog: "1.4.0 — Mapper coverage from real payloads: get_alerts now maps the Windows event-log payload sigma alerts carry (alert_subtype = eventlog), which was entirely unmapped — Defender 1116/1117 yields the malware name, classification, severity and provider, the detected file, the process that touched it and the acting user, plus the log provider and event code. Also added the agent IP, DNS domain, device type, agent version and groups, the tenant, the alert subtype and threat type, the string severity and the event time. get_threats gained the threat level (previously never reaching the OCSF document at all), the event time and the top agent's reachability. 1.3.1 — Flagged get_alerts as ingestion-ready (ingest hints: results_path/dedup/incremental on from_date) so it appears in the recommended ingestion commands when creating an instance. 1.3.0 — Response & triage expansion: kill/dump process, on-demand AV/YARA scans, file/service/scheduled-task deletion, quarantine management, threat-level isolation, job cancel/relaunch/wait; alert search (get_alerts) and full alert/threat triage (tag, comments, notes, status, level, history, details); exhaustive alert OCSF mappers; reworked get_threats mapper (fixed MITRE tactics map handling, full top-agent/user/rule and counts coverage, rule-based incident title/description). 1.2.2 — Documentation wording cleanup. 1.2.1 — Corrected the get_threats OCSF mapper to native threat fields (top_agents/top_impacted_users/top_rules/mitre_tactics) instead of enriched-only arrays; added agent.osversion to get_security_events. 1.2.0 — Added ingestion commands get_security_events (alerts) and get_threats with bundled OCSF mappers and ingest hints (results_path/dedup/incremental). 1.1.1 — Added test_connection for the instance Test button. 1.1.0 — Command names prefixed with 'harfanglab-' (e.g. harfanglab-isolate-endpoint) for easier toolbox search; command IDs unchanged. 1.0.0 — Initial release: endpoint/agent management, isolation, policy assignment, IOC & whitelist management, security-event triage, telemetry hunting (processes, network, DNS, authentications, binaries, event logs), threat hunting by hash, and forensic collection jobs (pipes, prefetch, run keys, scheduled tasks, drivers, services, processes, network, sessions, WMI, IOC scan, artifacts, RAM dump) with their result retrieval commands.
