v0.92.0

Added

• vendors/linkup: a client for Linkup's web search API. Search sends
  one Request, the query with one of four depths (flash, fast,
  standard, deep) and an output type (ranked results, a sourced answer,
  or an object that follows a JSON Schema), optionally narrowed to domains,
  a date range and a result count, and returns a Response holding what
  that output type answers. A status other than 200 is an *Error with the
  status, Linkup's error code and message, the refused fields and the
  Retry-After wait, and it matches exactly one of ErrBadRequest,
  ErrNoResult, ErrAuth, ErrInsufficientCredit, ErrRateLimited and
  ErrUpstream, so a rate limit that passes is told apart from exhausted
  credit that does not. The API key never appears in an error, also where
  Linkup's error body echoes it. Requests go through otel.HTTPClient
  unless WithHTTPClient replaces it, and nothing is retried, since every
  search is billed.

Changed

• typesafeai moves to vendors/typesafe, the directory that holds one
  client per third-party API, with its API unchanged. Import
  latere.ai/x/pkg/vendors/typesafe; the package name stays typesafe, so
  only the import path changes. The old path is removed, with no forwarding
  package.
