Convert "Reporting Guidelines" to proper section header

[Copilot]

Addresses review feedback on PR #6 requesting that "Reporting Guidelines" be formatted as a proper markdown header instead of bold text within a sentence.

Changes

• Converted **Reporting Guidelines** to ### Reporting Guidelines section header
• Removed redundant sentence referencing the guidelines
• Consolidated introductory text for better flow

After
