chore: add docstrings and field descriptions to Pydantic models

fern-api[bot] · web-flow · commit 2356727e8c76 · 2026-07-29T18:33:30.000Z
Enrich dozens of Pydantic model classes across the SDK with class-level
docstrings and per-field `description` arguments. No public API surface,
method signatures, or runtime behavior has changed — all additions are
purely documentation metadata surfaced via `pydantic.Field(description=…)`
and class-level docstrings.

Key changes:
- Add class-level docstrings to models including `Assistant`, `Call`, `BackoffPlan`, `CompliancePlan`, `ConversationNode`, `CampaignPaginatedResponse`, and many more
- Add `pydantic.Field(description=…)` to previously bare field declarations (e.g. `method`, `type`, `name`, `customer`, `error`) across tool, credential, and insight DTOs
- Update `User-Agent` header value to version placeholder `0.0.0-fern-placeholder` (internal SDK regeneration artifact)
