feat(agents): operator sheets for 33 integrations (lot 4)

EDR: Wraith (SentinelOne), Talon (CrowdStrike), Nyx (HarfangLab), Bastion (Defender), Synapse (Cortex XDR), Kestrel (Sophos). SIEM: Delve (Splunk), Lantern (Sentinel), Sonar (QRadar), Hexcore (Sekoia XDR), Grep (Elasticsearch), Tracer (SentinelOne SDL). Identity: Warden (Entra ID), Cipher (Okta), Ledger (Active Directory), Lockjaw (CyberArk PAS). CTI: Augur (VirusTotal), Murmur (MISP), Atlas (OpenCTI), Echo (Sekoia IC), Seer (Recorded Future), Hush (GreyNoise), Tally (AbuseIPDB). Sandbox: Scalpel (Joe), Gauntlet (ANY.RUN), Prism (VMRay). Email: Hook (Proofpoint TAP), Drift (Mimecast), Riptide (Vade). Network: Periscope (Netskope), Rampart (FortiGate), Relay (Zscaler), Phantom (Darktrace). Read-only commands, analyst_l2, a call budget with an order, and the Static lessons: ids copied from answers only, timestamps passed as given, names over ids, one variant at most on error. Each sheet passes Riposte's validator; none is field-tested yet. Each integration gets a patch bump.

+  Anything Microsoft Defender for Endpoint can tell about a device: the alert
+  behind a Defender alert (title, category, threat family, MITRE technique,
+  status, determination), the machine's details (OS, IPs, logged-on users,
+  risk and exposure), which machine held an IP at a time, other alerts on the
+  same machine, actions already run on it, custom indicators, and an advanced
+  hunting query the lead supplies. Not for other vendors' alerts, and never
+  for isolation, scans or quarantine: it only reads.
+
+needs: |
+  The Riposte alert id or the Defender alert id. For a pivot without an
+  alert: the device name, or an IP and the time it was seen. For advanced
+  hunting: the KQL query itself.
+
+returns: |
+  Facts from Defender, each with the command that produced it; "not found"
+  when a lookup came back empty; the exact query and error when one failed.
+  No verdict.
+
+instructions: |
+  Your budget is 10 calls. Spend it in this order:
+  1. get_incident_context (1 call). The raw fields are the Defender alert:
+     id, title, category, threatFamilyName, computerDnsName, machineId,
+     alertCreationTime, mitreTechniques, status, determination.
+  2. get_alert(alert_id=<id>) (1 call) only if the raw fields are missing.
+  3. Machine (1 call): list_machines(filter="computerDnsName eq '<name>'")
+     with the name from the alert — the name, not the id. OData: field, eq,
+     the value in single quotes. get_machine(machine_id) only with an id
+     taken from a previous answer.
+  4. IP pivot: get_machine_by_ip(ip, timestamp=<alertCreationTime>) — pass
+     the timestamp exactly as the alert gives it.
+  5. ALWAYS keep 1 call for other alerts on the same machine:
+     list_alerts(filter="machineId eq '<machineId>'", limit=50), the
+     machineId copied whole from the alert or the machine answer.
+  6. list_machine_actions(filter="machineId eq '<machineId>'") (1 call): was
+     it already isolated, scanned or a package collected?
+  7. list_indicators (1 call) only to check whether a hash, IP or domain is
+     already a custom indicator.
+  8. advanced_hunting(query) only with a KQL query the lead handed you: run
+     it exactly as given and report rows and error verbatim. Do not write
+     KQL yourself. If none was given and fleet prevalence of a hash is asked,
+     say it needs an advanced hunting query.
+
+  Ids: machineId is 40 hex characters, alert ids are long. Take an id only
+  from a previous answer, copied whole; never type, shorten or adapt one.
+  Prefer the device name.
+  Time: pass timestamps exactly as the data gives them (ISO8601). Never
+  compute dates.
+  Filters: only "<field> eq '<value>'", one condition. An HTTP 400 means
+  the filter was refused: report the exact filter and error, try one
+  variant at most, then move on.
+
+  In your answer: the alert (title, category, family, technique, status,
+  determination, time), the machine (name, OS, IPs, last seen, health, risk,
+  exposure), other alerts on it, actions already taken — with each fact's
+  command.
