Add folder-based structure support for MASTG-TEST files with method injection

[Copilot]

Enables folder-based test organization with multiple testing methods (static, dynamic, network) per test, maintaining backward compatibility with flat file structure.

Changes

• New hook: inject-test-methods.py

  • Scans for method-*.md files in test directories
  • Extracts type from frontmatter and injects content before "## Evaluation" section
  • Generates "## Method N - {Type}" headings automatically
  • Updates page metadata with aggregated types from all methods
  • Priority -35 (after ID extraction, before content processing)

• Navigation pattern update in mkdocs.yml

  • Changed from /*.md to /**/MASTG-TEST-*.md for all test categories
  • Matches both flat (MASTG-TEST-0202.md) and folder-based (MASTG-TEST-0202/MASTG-TEST-0202.md) structures

Structure Example

MASTG-TEST-0202/
  ├── MASTG-TEST-0202.md    # Main test file with Overview and Evaluation
  ├── method-1.md           # type: static
  ├── method-2.md           # type: dynamic
  └── method-3.md           # type: network

Each method file contains frontmatter with type and markdown content with ## Steps and ## Observation sections. The hook injects all methods before the Evaluation section in the main test file.

Technical Details

• Regex pattern supports Windows/Unix line endings: r'^---\s*(?:\r?\n)(.*?)(?:\r?\n)---\s*(?:\r?\n)(.*)$'
• Specific exception handling for UnicodeDecodeError, PermissionError, and OSError
• Type display mapping: static → Static Analysis, dynamic → Dynamic Analysis, network → Network Analysis
• Falls back gracefully when no "## Evaluation" section exists (appends at end)

This section details on the original issue you should resolve

<issue_title>Add support for folder-based MASTG-TEST</issue_title>
<issue_description>Currently, tests in tests-beta/ are structured like OWASP/mastg/tests-beta/**/**/MASTG-TEST-****.md.

We need to update this to OWASP/mastg/tests-beta/**/**/MASTG-TEST-****/MASTG-TEST-****.md similar to how our demos/ work. But still support OWASP/mastg/tests-beta/**/**/MASTG-TEST-****.md for backwards compatibility for now.

In addition to that, tests in the MASTG-TEST-****/ folders will support one or more testing methods.

Each method is a method-*.md file (e.g. method-1.md, method-2.md, etc.)

Some intro...

## Steps

...

## Observation

...

The automation will inject any existing methods into the main MASTG-TEST-****.md file before the Evaluation section.

Example:

ls OWASP/mastg/tests-beta/android/MASVS-STORAGE/MASTG-TEST-0202/
MASTG-TEST-0202.md
method-1.md
method-2.md
method-3.md
method-4.md

Would render as:
