Add comprehensive endpoint scanning and capabilities API system

[Copilot]

This PR implements a unified endpoint discovery system that scans and exposes all REST API endpoints and AI agent Verb methods across the Sentrius platform, enabling dynamic capability discovery for AI agents and Python clients.

Overview

The system provides a centralized way to discover what operations are available across all sub-projects, extracting descriptions, parameters, access limitations, and metadata from both:

• REST endpoints from Spring controllers with @LimitAccess annotations
• Verb methods from AI agent classes with @Verb annotations

Key Components

Data Models (core/src/main/java/io/sentrius/sso/core/dto/capabilities/)

• EndpointDescriptor - Unified descriptor for both REST and Verb endpoints
• ParameterDescriptor - Parameter information with types and sources
• AccessLimitations - Extracted @LimitAccess annotation data

Endpoint Scanning Service

• EndpointScanningService - Scans classpath for both controller methods and verb methods
• Extracts HTTP methods, paths, parameters, access control information
• Provides caching and refresh capabilities for performance

REST API (/api/v1/capabilities/)

• GET /endpoints - All endpoints with optional filtering by type/auth requirements
• GET /rest - REST endpoints only
• GET /verbs - AI agent verb methods only
• GET /refresh - Force cache refresh (requires admin access)

VerbRegistry Integration

Enhanced existing VerbRegistry with new methods:

• getVerbDescriptors() - Get endpoint descriptors for all verbs
• getAiCallableVerbDescriptors() - Get only AI-callable verb descriptors

Example Usage

For AI Agents

curl -H "Authorization: Bearer <token>" \
  "/api/v1/capabilities/verbs"

For Python Agents

response = requests.get("/api/v1/capabilities/endpoints")
capabilities = response.json()
for cap in capabilities:
    print(f"{cap['type']}: {cap['name']} - {cap['description']}")

Response Format

[
  {
    "name": "listusers",
    "description": "Returns list of users", 
    "type": "REST",
    "httpMethod": "GET",
    "path": "/api/v1/users/list",
    "accessLimitations": {
      "hasLimitAccess": true,
      "userAccess": ["CAN_VIEW_USERS"]
    }
  },
  {
    "name": "assess_ztat_requests",
    "description": "Analyzes ztats requests by prompting the LLM",
    "type": "VERB",
    "requiresTokenManagement": true,
    "metadata": {
      "isAiCallable": true
    }
  }
]

Features

• Unified Discovery: Single API to discover both REST endpoints and AI verbs
• Rich Metadata: Extracts descriptions, parameters, access requirements, HTTP methods
• Security Aware: Properly handles and exposes @LimitAccess restrictions
• Performance Optimized: Caching with manual refresh capability
• Filterable: Support for filtering by type, authentication requirements
• Extensible: Easy to extend for additional endpoint types or metadata

Testing

• Unit tests for core scanning functionality
• Integration tests for full Spring context scanning
• Comprehensive documentation with usage examples

This enables the dynamic population of Verb annotations and makes capabilities available to Python agents as requested in the issue requirements.

Fixes #74.

Firewall rules blocked me from connecting to one or more addresses

I tried to connect to the following addresses, but was blocked by firewall rules:

• repository.jboss.org
  • Triggering command: /usr/lib/jvm/temurin-17-jdk-amd64/bin/java --enable-native-access=ALL-UNNAMED -classpath /usr/share/apache-maven-3.9.10/boot/plexus-classworlds-2.9.0.jar -Dclassworlds.conf=/usr/share/apache-maven-3.9.10/bin/m2.conf -Dmaven.home=/usr/share/apache-maven-3.9.10 -Dlibrary.jansi.path=/usr/share/apache-maven-3.9.10/lib/jansi-native -Dmaven.multiModuleProjectDirectory=/home/REDACTED/work/Sentrius/Sentrius org.codehaus.plexus.classworlds.launcher.Launcher clean compile -DskipTests (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to my firewall allow list
