Fix deep hierarchical parsing to detect all API endpoints in large projects (Flask, FastAPI, Django)

[Reprompts]

Description:
Currently, PyApptest’s autodetection logic works up to a limited folder depth or is restricted by current recursive traversal limits.
This causes a major problem for large real-world projects where API endpoints (routes/views) are deeply nested inside multiple folders or submodules.

Problem Example:

project/
app/
modules/
users/
routes/
user_routes.py --> ❌ Missed currently

Endpoints inside files like user_routes.py are currently not detected by the system!

Objective:

Fix the recursive directory traversal so that all levels of the project hierarchy are searched properly.

Ensure endpoint parsers for:

Flask (Blueprints)

FastAPI (Routers and APIRouters)

Django (urls.py with include())

are able to detect nested APIs properly.

Tasks:

Refactor the code that walks through the project directory:

Use os.walk() (Python) or equivalent method to recursively traverse all folders without depth limit.

Handle symbolic links safely (to avoid infinite loops).

Update internal parsers:

For Flask: Parse nested Blueprint registrations and route handlers.

For FastAPI: Parse nested include_router() usages.

For Django: Parse all chained include() patterns inside urls.py files.

Create unit test projects:

Small dummy Flask/FastAPI/Django projects with deeply nested APIs.

Validate that all endpoints are now detected correctly.

Update error handling:

If a Python file is not parsable or errors occur during detection, skip gracefully but log the issue.

Acceptance Criteria:

All endpoints are detected regardless of how deep they are nested.

No missing endpoints during parsing.

No crashes if irrelevant Python files are encountered.

Why This Matters:

Real-world projects are modular and deeply structured.

Missing endpoints leads to incomplete API testing and broken developer trust.

Makes PyApptest much more robust and production-ready.

Optional Bonus:

Allow setting a "max depth" parameter optionally (for super-large projects where unlimited recursion is risky).

Example:

config option

MAX_DEPTH = None # None = infinite
Allow setting it via config file (.pyapptestconfig.json) or environment variable.
