Document new IModule lifecycle hooks and update module inventory

[antosubash]

Summary

This PR updates documentation to reflect new lifecycle hooks added to the IModule interface and provides a more comprehensive list of available modules in the framework.

Key Changes

• Expanded IModule interface documentation across three documentation files:

  • Added four new configuration hooks: ConfigureFeatureFlags, ConfigureAgents, ConfigureRateLimits, and ConfigureHost
  • Clarified that IModule defines "a set of lifecycle hooks" rather than specifying "six"
  • Added detailed descriptions and execution timing for each hook in reference tables

• Updated module inventory in README.md to reflect the current module ecosystem:

  • Expanded from 9 modules to 16 modules
  • Added: Agents, BackgroundJobs, Email, FeatureFlags, Localization, Marketplace, Rag, RateLimiting, Tenants
  • Reorganized list for better readability

• Clarified frontend architecture in getting-started guide:

  • Updated description of how the host app renders initial HTML to be more accurate (Inertia.js middleware instead of Blazor SSR)
  • Clarified the hydration flow with embedded JSON props

Notable Details

• All new hooks follow the existing pattern of virtual methods with default no-op implementations
• Documentation maintains consistency across guide, API reference, and constitution documents
• Execution timing and use cases are clearly documented for each hook
