[Feature] Generate API reference for @o2s/framework

[tomaszpacior]

Is your feature request related to a problem? Please describe.
The framework exports modules, models, and an SDK, but there is no auto-generated API reference for @o2s/framework. Consumers need to inspect source code directly to discover available types, interfaces, and service methods, which slows onboarding and increases integration mistakes.

Describe the solution you'd like
Generate and publish TypeDoc documentation for @o2s/framework as part of the docs workflow. At minimum, provide an index of all module services and their methods (including parameters and return types) so consumers can discover extension points without reading implementation files.

Additional context (if applicable)

• Phase: 0.5 — Consumer Extension Points
• Source: high/
• Related note: this could enable automated descriptions of modules and normalized data models in docs, potentially assisted by AI generation.
