Note

Medium Risk
Medium risk because the Gmail toolkit is bumped to 5.0.0 with changed tool parameter contracts (new cc, revised UpdateDraftEmail optionality/behavior) which may affect downstream consumers relying on the previous schema.

Overview
Updates generated integration/toolkit metadata: removes the Tavily entry from the search integrations nav, bumps AshbyApi from 0.2.1 to 0.3.1, and bumps Gmail from 4.2.1 to 5.0.0 (updating all fullyQualifiedName versions and timestamps).

The Gmail toolkit definitions change notably by adding an explicit cc parameter to reply/draft-reply tools, refining bcc behavior descriptions, and making UpdateDraftEmail fields optional with new semantics for preserving/clearing headers; several embedded codeExample blocks are removed and the generated summary is marked stale (summaryStale, summaryStaleReason).
