[BUG] Only markdown is recognized as a valid format for README files

[meyrevived]

Bug Description

When scanning Konflux-ci/multi-platform-controller AgentReady score for the repo was falsly low due to a README.md file not existing or detailed enough. However, a README.adoc (AsciiDoc) exists with project overview, architecture, allocation strategies, OTP server, and cleanup docs.

To Reproduce

1. Clone Konflux-ci/multi-platform-controller
2. Run AgentReady scan using the uvx command
3. Review the results

Expected Behavior

Findings in README Structure reflect the existence of README files in various formats.

Actual Behavior

AgentReady only searches for README.md, giving this section of the report a 0/100 score.

Environment

• OS: Fedora CSB 42 (64 bit)
• Version: v2.40.0
• Python Version: 3.14.4
