feat(api): update API spec from langfuse/langfuse 8242934

[langfuse-bot]

Greptile Summary

The PR updates the generated API surface for logical-root observation filtering and moves score creation to the canonical scores resource while adding legacy compatibility aliases.

• Adds isRootObservation to observation models and sync/async list filters.
• Adds canonical sync/async score-create clients, raw methods, models, and package exports.
• Redirects legacy high-level score creation and legacy score types to their canonical equivalents.

Confidence Score: 3/5

The PR should not merge until legacy raw-response score creation remains available alongside the high-level compatibility alias.

Removing create from both legacy raw clients while continuing to expose them through with_raw_response causes existing raw-response score creation calls to fail immediately with AttributeError.

### Issue 1
langfuse/api/legacy/score_v1/client.py:54-56
**Legacy raw create is missing**

When callers use `client.legacy.score_v1.with_raw_response.create(...)`, `with_raw_response` returns a legacy raw client whose `create` method was removed, causing an `AttributeError` instead of creating the score and returning its HTTP response.
