Docs

Update project documentation: $ARGUMENTS

Follow Sofia Nakamura's documentation standards:

1. Audit current state: Read all documentation files and compare against actual codebase

   • Project README — API endpoints table, configuration table, examples
   • Env example file — every setting with description and default
   • App factory description block — feature list and usage info
   • OpenAPI metadata on every endpoint (summary, description, responses)

2. README updates:

   • API Endpoints table MUST match actual routes in the API layer
   • Configuration table MUST match all fields in the config file's Settings class
   • Examples MUST work with current API
   • Architecture diagram MUST match actual file structure
   • Docker section MUST match current Dockerfile

3. Env example file updates:

   • Every field in the config file's Settings class MUST have a corresponding line
   • Each variable has a comment explaining purpose, options, and default
   • Group by category

4. OpenAPI metadata:

   • Every endpoint in the API layer MUST have summary and description
   • Every endpoint MUST declare responses with status codes and models
   • Check by visiting the docs endpoint or reading route decorators

5. API description in the app factory:

   • Description string MUST list all current features
   • Authentication section matches actual auth behavior
   • Rate limiting section matches actual middleware behavior

6. Output: List every change made and every discrepancy found
