🌿 Fern Regeneration -- April 21, 2026

[fern-api]

This PR regenerates code to match the latest API Definition.

---

Note

Medium Risk
Regenerates large portions of the auto-generated SDK and expands multiple client method signatures, which can introduce subtle breaking changes for downstream users even though the logic is mostly mechanical.

Overview
Bumps the SDK to 2.44.0 (including User-Agent/X-Fern-SDK-Version) and updates dependencies (e.g. packaging 26.0 → 26.1).

Expands the API surface: adds conversational_ai.secrets.get, adds search filtering to conversational_ai.secrets.list, adds sharing_mode filtering to conversational_ai.tests.list, and introduces conversational_ai.tools.executions.get for listing tool executions.

Updates several models/parameters used across clients and docs, including speech_to_text.convert(..., detect_speaker_roles=...), MCP tool config overrides now accept response_mocks and return McpToolConfigOverrideOutput, and Studio quality_preset is unified to QualityPresetType. Reference docs are regenerated accordingly (deprecations/parameter notes, and removal of avatar_context mentions).
