refactor: remove rust-based agent templates and standardize worker unit naming

[l50]

Key Changes:

• Removed all Rust-based agent and orchestrator Warp Gate templates and documentation
• Updated all EC2 and Ansible deployment scripts to use ares@{role}.service systemd unit naming instead of ares-worker@{role}.service
• Standardized GPU template documentation and references for agent images
• Improved Ansible lint configuration to exclude external collection-dependent paths

Added:

• Exclusion of playbooks and meta directories in Ansible lint config to avoid errors when external collections are unavailable locally

Changed:

• Worker systemd unit naming standardized from ares-worker@{role}.service to ares@{role}.service across all EC2 deployment scripts, status checks, and environment reloads
• Ansible role for Redis now deploys ares@.service template instead of ares-worker@.service
• Documentation for GPU agent templates now references ares-cracker-agent-gpu consistently, dropping the "rust" prefix
• Minor documentation corrections to blue agent templates, ensuring consistent naming with the new convention and removing references to "Rust" agent variants
• Improved comments and inline documentation for excluded Ansible lint paths

Removed:

• All Rust-based agent and orchestrator Warp Gate templates and associated documentation:
  • ares-rust-worker, ares-rust-orchestrator, ares-rust-blue-agent, ares-rust-blue-triage-agent, ares-rust-blue-threat-hunter-agent, ares-rust-blue-lateral-analyst-agent
  • ares-rust-recon-agent, ares-rust-cracker-agent, ares-rust-cracker-agent-gpu, ares-rust-credential-access-agent, ares-rust-lateral-movement-agent, ares-rust-privesc-agent, ares-rust-acl-agent, ares-rust-coercion-agent, ares-rust-cli
  • All associated warpgate.yaml files and Markdown READMEs in warpgate-templates/templates/ares-rust-*
• Systemd template for ares-worker@.service (now replaced by ares@.service) in all roles and EC2 setup scripts
