FoundryClient not initialized with preview=True, orchestration commands fail

[anjor]

Problem

The TokenAuthProvider.get_client() creates a FoundryClient without preview=True. Many v2 API endpoints (especially orchestration/builds) require preview mode and fail with ApiFeaturePreviewUsageOnly error.

Reproduction

pltr orchestration builds search
# Fails with: ApiFeaturePreviewUsageOnly

Root Cause

In src/pltr/auth/token.py:

return FoundryClient(auth=auth, hostname=self.host)

Should be:

return FoundryClient(auth=auth, hostname=self.host, preview=True)  

The ?preview=true query parameter also needs to be added to direct API calls. The SDK passes this automatically when the client is created with preview=True.

Workaround

Call the API directly with ?preview=true query parameter.
