v0.19.1

Fixed

• The routines page failed to load with "missing field prompt". PR #825
  made GET /routines omit the prompt field from each routine's JSON by
  default, but the UI's separately-mirrored Routine struct never got a
  matching #[serde(default)] on that field, so the wasm client's
  deserialization broke on every list fetch.

Added

• Repository filter for the Routines table. The REST GET /routines
  endpoint has supported a ?repository= filter for a while, but the web UI
  had no way to use it — the only client-side facets were status, agent, and
  machine. Added a REPOSITORY dropdown to the Routines filter bar (mirroring
  the existing agent/machine facet pattern), populated from the distinct
  repository URLs across loaded routines, so operators can narrow a dense
  routines list to a single repo without hand-editing the query string.
