fix: resolve based_on schema/serialization issues in reflect API (#348)
* fix: add default values to OpenAPI schema for default_factory fields

This commit fixes the OpenAPI schema to include default values for fields
using default_factory, which improves schema accuracy and client generation.

Changes:
1. Added FieldWithDefault() helper to inject default values into OpenAPI schema
2. Updated 14 fields using default_factory to include defaults in schema:
   - ReflectBasedOn.{memories, mental_models, directives}
   - ReflectTrace.{tool_calls, llm_calls}
   - All tags fields
   - All trigger fields
   - All include fields

3. Regenerated OpenAPI spec with proper defaults

4. Added tests to verify API returns correct format with empty banks

Note: This fixes the schema but doesn't change the v0.3.0 -> v0.4.0 breaking
change where based_on went from list to object. Clients should handle both
formats for backward compatibility.

* fix: remove client imports from API test

The test was failing in CI because it imported the client library
which isn't installed in the API test environment.

Changed to test only API JSON response format, not client parsing.
This is more appropriate for an API test anyway.

* test: add client tests for ReflectResponse parsing

Added comprehensive tests in hindsight-clients/python/tests to verify:
- v0.4.0+ format with empty based_on object
- v0.4.0+ format with null based_on
- v0.4.0+ format with populated facts
- v0.3.0 format (list) correctly fails validation
- Missing based_on field handling

These tests document the v0.3.0 -> v0.4.0 breaking change where
based_on changed from list to object.

Test reflect endpoint with empty based_on (no memories scenario).
This test verifies that the API returns the correct based_on format:
- v0.3.0 (old): returned based_on as list []
- v0.4.0+ (current): returns based_on as object {"memories": [], "mental_models": [], "directives": []}
