Note

High Risk
Adds credential vault APIs and changes vault operation retry semantics on security-sensitive paths (secrets, browser fill, collection URLs).

Overview
Release 0.103.0 bumps the package version and expands the vault and config-registry surface in the generated SDK.

Credential vault items are first-class: new types and params for create/update (upsert / update with type="credential", optimistic version, optional expected_item_id), collection flows (collect operation, CredentialCollectionAction), and item GET/list docs for pending collection and wait. perform_operation fill now uses unified VaultFillFieldParam (replacing card-only fill params), supports credential field names and TOTP behavior, and makes page_url optional when exactly one browser page is open (cards still require HTTPS URLs).

Vault operations no longer use the client’s automatic HTTP retries—perform_operation posts with max_retries=0 so ambiguous fill/collect outcomes are not double-applied; ordinary vault reads still honor max_retries (covered by new tests).

Managed auth field models gain optional input_mode (text, email, tel, numeric) for keyboard hints.

Lookup and config registry responses add required working_configurations, ordered with the recommended config first.
