[Logger] Add markdown output and fix suggestions to log output

[TrueNine]

Bug Description

Logger output should be more user-friendly for debugging. Currently:

1. Logs output only JSON format which is hard to read
2. Missing fix suggestions for WARN/ERROR/FATAL levels
3. JSON errors not displayed as friendly multi-line markdown

Steps to Reproduce

1. Run CLI with some config errors
2. Observe JSON-only log output
3. Try to understand the error and how to fix it

Expected Behavior

• Log output should support markdown format that can be easily copied
• WARN/ERROR/FATAL logs should include actionable fix suggestions via an extra parameter
• When errors occur, JSON should display as friendly multi-line markdown with proper indentation
• Example expected output:

  - { $: [11:20:36.990, INFO, defineConfig], _: {...} }
  - { $: [11:20:36.993, WARN, defineConfig], _: {...} }
  - { $: [11:20:38.378, ERROR, defineConfig], _: {...} }
  

Actual Behavior

• Current logger only outputs JSON
• No fix suggestions provided
• Hard to copy/understand for AI debugging
