v0.6.0

The APL server and the React client now live in a single repository, and this is
the first release built from that one tree. ewc-v0.6.0.zip on the release page
is a runnable tree: the server, the demos and a built client together.

Upgrading

• Download ewc-v0.6.0.zip.
• Building from a clone is yarn install then yarn build at the repository
  root. Yarn, not npm: the JavaScript tooling is a yarn workspace, and one
  install at the root covers both halves. client/dist/ is no longer committed.
• The demo moved from demo/ to test-apps/demo/. Update any
  ]link.create #.demo <repo>/demo to <repo>/test-apps/demo.
• Do not ]link.create the repository root. It walks client/node_modules,
  where package names collide as APL names and abort the whole link. Link EWC/
  and test-apps/demo/ by name instead; EWC.FOLDER still resolves itself.
• A sibling ewc-client/ or jswc-client/ checkout is no longer searched for a
  client build. With the client in the same repository, a leftover sibling would
  silently shadow it.

New

• One repository. The APL server, the demos, the User Guide and the React client
  are versioned, tested and released together, so a change spanning both halves
  is a single pull request rather than a pair.
• Plugins: applications can register their own components at runtime with
  EWC.RegisterPlugin, contributing EWC classes, static resources to serve and
  client JavaScript to inject. A charting or dashboard library of your choice no
  longer has to wait for Dyalog to add it.
• Trackbar and ColorButton classes.
• Static: the plain positioned container that pre-dates SubForm and Group,
  with no caption and no etched frame, for older applications that build their
  own panels out of it.
• Locator: the user positions an outline and the Locator event (80) reports
  where they put it, replying (name 80 y x h w) as ⎕DQ does natively.
• Subsidiary windows. A non-primary Form in Browser and Multi modes renders as
  a floating window over the primary one, with a titlebar, its Caption, a close
  box and drag, rather than as a browser popup. Desktop mode is unchanged.
• CBits and KeepBits on Bitmap: an image supplied as a colour-bit matrix
  now renders.
• AutoConf and Attach: an object reconfigures when its parent resizes, with
  each edge either pinned or proportional, and Configure (31) is reported.
• PORTTRIES: when PORT is busy, EWC moves up to the next free port (ten by
  default, the way Vite steps from 5173), says which one it took, and leaves it
  in EWC.PORT. Set EWC.PORTTRIES←1 to insist on PORT and have Init
  signal an error instead. The Vite dev server can be aimed at a second server
  with ?aplPort= or ?aplUrl=.
• test-apps/: EWC applications that the Playwright suite drives. multitest
  joins the demo, with an extensive suite covering Multi mode.
• Reference documentation is regenerated and deployed by an action, carries the
  Dynamic flag per property, and links to the Dyalog 20.0 documentation.

Improved

• Mouse events report positions correctly, relative to the object that raised
  them.
• Event names are matched case-insensitively, as ⎕WC does. An application that
  wrote 'mousedown' was silently ignored before.
• Active 0 greys out menus, menu items, ColorButton and Trackbar rather
  than being ignored. It is how applications disable a command.
• A Form's Caption sets the browser tab title.
• Menu styling and layout refinements, including menu-bar items.
• Edit: the cursor no longer jumps while typing into a field with restricted
  input.
• ∆DQ: eDQ '.' (dequeue every object) works again, and processing an event
  for an existing ID no longer exits ∆DQ.
• wss.aplc logs go through EWC's own logging, and its timeout handling is more
  defensive.
• Assorted layout and styling fixes across components.
