feat: Add New Relic, Splunk, and ServiceNow integrations

Rust Tool Implementations:
- newrelic.rs: 6 tools (NRQL query, alerts, incidents, entity search, metrics, incident ack)
- splunk.rs: 6 tools (search, alerts, saved searches, HEC send, indexes)
- servicenow.rs: 6 tools (incident CRUD, CMDB query, change create)

Feature Flags:
- observability: New Relic tools
- siem: Splunk tools
- itsm: ServiceNow tools

Documentation:
- Tools reference pages: newrelic.md, splunk.md, servicenow.md
- Agent Library: Added ITSM domain (itsm.md) with 3 agents
- Agent Library: Updated observability.md with newrelic-ops, splunk-analyst
- Wired into Docusaurus sidebar

Example Agents:
- newrelic-ops.yaml: Comprehensive New Relic observability agent
- splunk-ops.yaml: Splunk log analysis and SIEM agent
- servicenow-ops.yaml: ServiceNow ITSM automation agent

Closes #83
