Finalize System Automation Hub Setup and Quality Improvements

[ruhdevops]

I have successfully set up and finalized the System Automation Hub in this environment.

Key improvements and actions taken:

• Environment Configuration: Installed PowerShell Core (v7.6.0) and essential modules (Pester for testing, PSScriptAnalyzer for linting) to ensure a complete automation development environment.
• Bug Fixes: Resolved a pathing issue in the Pester test suite (tests/Project.Tests.ps1) to ensure it works correctly on Linux and other platforms.
• Code Quality & Linting:
  • Fixed multiple PSScriptAnalyzer warnings across several scripts.
  • Standardized all PowerShell scripts to use UTF-8 with BOM encoding for better tool compatibility.
  • Renamed variables that conflicted with PowerShell's automatic variables (e.g., $matches and $profile) to prevent runtime issues.
• Performance Optimization: Implemented the 'Early Response' pattern in the webhook listener (webhooks/listener.ps1) to minimize response latency for external callers like GitHub.
• Verification:
  • Confirmed the webhook listener successfully receives and parses JSON payloads.
  • Validated that all 12 Pester tests pass in the final environment state.
• Clean-up: Merged all changes into the main branch and ensured a clean repository state.
