v0.8.4

• The bundled stream data come from the tables link builds with its default configuration,
  with upstream area and precipitation from fwapg, instead of bcfishpass's views (#87). This
  covers inst/testdata/streams.gpkg and the streams layer of inst/vignette-data/pars.gpkg.
  The build scripts pin the link run they read and stop when it has moved. The shipped
  columns change:

  • segmented_stream_id (character) is replaced by id_segment (integer), which is unique only
    together with the new watershed_group_code column;
  • spawning and rearing are logical, not integer codes, so fl_valley_join(cols = NULL) now
    picks them up on the bundled tile;
  • linear_feature_id is added, and rows are ordered by blue_line_key and
    downstream_route_measure.

  inst/NOTICE.md credits each column to its source. A bcfishpass credit remains for access and
  habitat, because link's default configuration applies bcfishpass's override tables.

• The Parsnip article is rewritten to open with its answer: 40,640 ha of floodplain at flood
  factor 4, 7.3 % of the watershed group (#92). Every number in it is computed from the article's
  data, which its data script pins by digest, and a check fails when a quoted claim stops holding.
  A table gives the floodplain area at flood factors 2, 4, 6 and 7.

• flooded is cited with its Zenodo concept DOI, 10.5281/zenodo.23302790, which
  citation("flooded") now prints. CITATION.cff names the maintainer as the only author and
  New Graph Environment Ltd. as publisher.
