v0.16.1

Oriel 0.16.1

Added

• System monitor example: an Applications list, the default in all
  three renderers. Each desktop app shows its combined CPU, summed resident
  memory, threads and process count; Show processes opens its members
  as a parent/child tree, and All processes lists everything, as
  before. Apps are recognized from desktop entries (Linux), .app bundles
  (macOS) and window owners (Windows), with process ancestry. Its CI runs
  the model tests and builds the Oriel renderer on Windows and macOS.

Fixed

• oriel.chat: a Stop that comes after its reply ended no longer stops
  the next one. Tokens can reach the page in a burst after the model
  finished, and cancel() with no reply running stops the next to start,
  so a Stop pressed during the burst left the next message empty.
  chat:token events now carry their reply's id (reply), and
  cancelReply(id) stops that reply only while it runs; the showcase's
  Stop sends it. cancel() is unchanged.
• The showcase's chat UI test (iOS CI) no longer waits 5 minutes for a
  reply its own late Stop had cancelled: it stops only while the reply
  runs, and asks again after a reply with no tokens.
• System monitor (Oriel renderer): picking a sort key (CPU, Memory, ...)
  no longer flips the direction; only the direction button does, as in the
  web frontend.
