Enhance license header script and update README

[KCoderVA]

This pull request updates the repository to improve license header automation, metadata handling, and documentation clarity. The main focus is on making the license header script more flexible and generic so it can be reused across projects and by different users, while also cleaning up and streamlining the setup guide.

License Header Automation Improvements:

• The Add-LicenseHeaders.ps1 script now supports additional file types (md, txt, bat, psm, json) and allows users to inject custom metadata such as author name, email, organization, team, project name, license type, and compliance note. Metadata is auto-detected from Git config or environment variables if not provided. [1] [2]
• License header templates have been refactored to use generic placeholders populated with user/project metadata, replacing hardcoded references to the original author and organization. The script now marks generated headers for easier identification.
• The logic for detecting existing headers has been updated to look for generic indicators rather than specific author/organization names, reducing false positives and making the script more broadly applicable.
• Logging in the header script now reflects the actual metadata used for each run, improving traceability and clarity.
• File discovery in the header script is more robust, properly handling cases where no files are found for a given extension.

Documentation and Setup Guide Updates:

• The README.md has been cleaned up to remove hardcoded copyright/license blocks, clarify the quick start and local setup instructions, and streamline guidance for accessing the interactive and printable guides. [1] [2] [3] [4]

Versioning:

• The license header script version has been bumped to 1.0.1 to reflect these improvements.

These auto-detection lines are difficult to read and maintain due to complex nested conditionals on single lines. Consider refactoring into a helper function or breaking into multiple lines for better readability.

The regex patterns use ^ anchor which matches start of string, but $ContentText is a multiline string joined with newlines. These patterns will only match if the license header is at the very beginning of the file. Consider using multiline mode (?m)^ or \n to match line starts within the content.

Suggested change

	$ContentText -match '(^/\*.*?(Licensed under|Copyright).*?\*/)' -or # block comment with license
	$ContentText -match '(^<#.*?(Licensed under|Copyright).*?#>)' # ps1 block comment with license
	$ContentText -match '(?m)^/\*.*?(Licensed under|Copyright).*?\*/' -or # block comment with license
	$ContentText -match '(?m)^<#.*?(Licensed under|Copyright).*?#>' # ps1 block comment with license
