WCS 0.1.0

The first release without the preview suffix. It is distributed as source, like the preview, and the
rules of versioning and compatibility apply from here:
a patch never breaks what that page lists; a minor may, and says so in this file.

Added

• WMS contract: two optional routes, 44 and 45; a WMS that does not offer them answers 404 or
  501 and the WCS behaves as before. POST reservations/cell/check
  (IWarehouse.CheckStorageCellAsync): whether the warehouse would reserve a precise cell, without
  reserving it. POST notes/missing-among (IWarehouse.GetMissingNoteAssignmentsAsync): which of the
  given shipping-note assignments no longer exist. Both have a default implementation in IWarehouse,
  so an existing adapter keeps compiling. Wcs.ContractCheck treats an added optional operation as
  compatible.

Fixed

• Engine: an extraction still in its cell sent to a precise cell the warehouse refuses stays the
  extraction it was: the cell is checked (route 44) before the warehouse is told about the change of
  cell, which used to close the mission when the reservation was refused afterwards.

• Engine: the queued row of a shipping-note assignment deleted in the WMS leaves the extraction queue
  (route 45) instead of moving a load unit nobody asked for.

• Engine: «does this process have handled load units?» also answers for the months that left the
  history retention: their references are kept in wcs.db before the month file is deleted.

• Wcs.Wms.Client: an enum answer the contract does not know (an outcome of a newer WMS) is a
  permanent rejection, not the value of the caller's «anything else» branch.

• Engine: the second extraction trigger point selects the storing missions coming from its own
  group; it compared against the first point's group, so with only the second point loaded every
  storing mission was received.

• Engine: a loaded source whose load unit has no route yet no longer hides the sources after it
  from the device that receives from them.

• Engine: updates and removals of commands and extraction queue rows are announced to the event
  hub only after the save succeeds, as insertions already were.

• Host: PUT /api/v1/plant/graph with a null list or a null entry, and
  PUT /api/v1/items/geometry with a null entry, answer 400 instead of 500.

• Wcs.Api.Client: a BaseAddress that is not a bare http(s) origin is refused when the client
  is built; a successful response with a null body is a WcsApiException naming the request.

• Wcs.DbTool: verify and restore refuse a manifest whose file names are not bare WCS
  database names, are listed twice, or whose format is unknown, before touching any file.

• Release workflow: the --prerelease switch and a single release file reach gh whole. They
  were splatted one character at a time, so the draft release of 0.1.0-preview.1 was not
  created (it was created by hand from the same tag).

Changed

• Host: a warning at startup when Wcs:ApiKey or Wcs:ReadOnlyApiKey is shorter than 32
  characters.
• Engine: transit times (GET /api/v1/log/transit-times) read each month once, with one query
  instead of three: about four times faster on a month of 200,000 log rows.
• Engine: a group's loading decision reads the load units ready to load once, instead of up to
  four times.
• Wcs.Api.Client disposes every HTTP response; the host compares API keys without allocating.
