feat: Migrate codegen to use use Blueprint

[razor-x]

Summary

This PR migrates the Python SDK code generator from parsing raw OpenAPI schemas to using the Blueprint specification that is already available in Metalsmith metadata. This eliminates the need for frozen output-parity workarounds and simplifies the codebase by removing temporary OpenAPI parsing utilities.

Key Changes

• Removed OpenAPI parsing dependencies: Deleted temporary files that were verbatim ports from the previous generator:

  • openapi/get-parameter-and-response-schema.ts
  • openapi/deep-flatten-one-of-and-all-of-schema.ts
  • openapi/flatten-obj-schema.ts
  • openapi/map-parent-to-children-resource.ts
  • openapi/get-filtered-routes.ts
  • openapi/types.ts
  • map-python-type.ts
  • endpoint-rules.ts

• Refactored route generation (codegen/lib/routes.ts):

  • Now driven entirely by blueprint.routes and blueprint.namespaces instead of OpenAPI paths
  • Simplified class and namespace mapping using Blueprint's path-based structure
  • Removed complex parent-child resource mapping logic in favor of Blueprint's parentPath relationships
  • Filters routes and endpoints using Blueprint's isUndocumented flags instead of OpenAPI extensions

• Created new type mapping module (codegen/lib/python-type.ts):

  • Replaces the old OpenAPI-based type mapping with Blueprint-aware functions
  • mapParameterToPythonType() and mapPropertyToPythonType() use Blueprint's format system
  • Handles special cases like Batch resource properties and list item formats

• Updated models layout context (codegen/lib/layouts/models.ts):

  • Now uses blueprint.resources, blueprint.events, and blueprint.actionAttempts directly
  • Simplified property merging for action attempt and event variants
  • Removed OpenAPI schema flattening logic

• Type refinements (seam/routes/models.py):

  • Changed ActionAttempt.result from Any to Dict[str, Any]
  • Updated Batch resource list properties from List[Any] to List[Dict[str, Any]]
  • Changed Device.device_type from Any to str
  • Changed Device.properties from Any to Dict[str, Any]
  • Removed deprecated PhoneRegistration dataclass
  • Changed ThermostatSchedule.max_override_period_minutes from int to float
  • Changed UnmanagedDevice.device_type from Any to str
  • Removed AbstractAcsEncoders class (moved to simulate submodule)
  • Updated various limit parameters from Optional[int] to Optional[float]
  • Reordered method parameters in AcsUsers.get() and Events.get() for consistency

• Route file updates:

  • Added workspaces.update() method
  • Updated parameter types across multiple route files to use float instead of int for pagination limits
  • Added missing imports (e.g., AcsEncodersSimulate in acs_encoders.py)

Implementation Details

• The generator now uses Blueprint's path-based namespace system (toNamespace() function converts paths like /acs/encoders to acs_encoders)
• Child class relationships are determined by comparing parentPath values from Blueprint entries
• Parameter and property type mapping is simplified by using Blueprint's standardized format system instead of parsing OpenAPI schemas
• The migration maintains backward compatibility with generated output while removing technical debt from the previous generator's workarounds
