Subject: [PATCH] =?UTF-8?q?Fix=20workspace=20deletion=20=E2=80=94=20use=20?=
 =?UTF-8?q?build=20transition=20API?=
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The plain DELETE endpoint returns 405 for stopped workspaces. Use
POST /workspaces/:id/builds with {"transition":"delete"} instead,
which is the correct Coder API for workspace deletion.
