v1.6.0 — Desktop builds + sprite picker views

The TMS9918 Editor is now a desktop app for macOS, Windows and Linux — and the
sprite picker gained two new layouts. The web editor is unchanged and still lives at
acwright.github.io/TMS9918-EDITOR.

The desktop app

One renderer behind two shells — everything the web app does, the desktop app does. What
it adds:

• A real menu bar, following the open project: a Sprite project says "Fill the
  sprite", a Multicolor project greys the pattern items, and the project list greys
  everything but New project. The keyboard map is unchanged and still lives behind ?.
• Native save and open dialogs. Every export — assembly, BASIC, binary, PNG, project
  JSON — goes through the system save sheet, each kind remembering the folder you last
  used, instead of landing in ~/Downloads. Importing a project opens a real file panel.
• Its own storage, in the app's userData directory rather than a browser profile,
  flushed to disk on the way out — an edit made a moment before you quit is there on
  relaunch.
• A window that remembers itself, including which display it was on.

Desktop projects are separate from the web app's. Move one across with Download and
Upload in the project list, or a share link.

Sprite picker, three ways

The sprite picker now matches the character set panel's three arrangements:

• Sheet — the whole set as one scaled picture, as before.
• Grid — fixed-size slots that wrap to the column width, so an 8×8 set is legible
  rather than 16 slots across a 440 px column.
• List — one row a slot, carrying its number in both bases, the hardware patterns it
  occupies (pat 12 at 8×8, pat 48–51 for a 16×16 quad), its colour by name, and
  whether it is Blank (no pixels set) or Invisible (colour 0). The sheet cannot
  tell those two apart; a row can.

The choice is remembered, and is independent of the character set's layout.

Also

• Both editors' Pages deploy is fixed — it had been publishing nothing since the renderer
  moved under src/renderer/.
• CI now builds the Electron main and preload processes, which nothing gated before.
