Add Flowtriq DDoS Attack Status check script

[jacob-masse]

Summary

• Adds Linux_Flowtriq_DDoS_Status.sh, a TacticalRMM check script for nodes running ftagent (Flowtriq's DDoS detection agent)
• Queries the local ftagent health endpoint (default 127.0.0.1:9100) and returns exit 1 if a DDoS attack is active or if the agent is unreachable; exit 0 when clear
• Registers the script in community_scripts.json under TRMM (Linux):Checks
• No external dependencies beyond curl; parses the JSON health response with standard shell tools (no jq required)

Script behaviour

Condition	Exit code
No attack, agent healthy	0
Attack active	1
Agent unreachable	1
Baseline not ready (when warn_no_baseline=1)	1

Arguments

• port=9100 - ftagent health port (default 9100)
• timeout=5 - curl timeout in seconds
• warn_no_baseline=0 - set to 1 to alert when baseline detection is not yet ready

Test plan

• Run against a node with ftagent running and no attack - should exit 0
• Run with ftagent stopped - should exit 1 with "unreachable" message
• Run python3 -m json.tool community_scripts.json passes (JSON valid)
