v0.11.0

The display release: a subdomain can now be an app. A pixel
framebuffer runs wasm cartridges (Redox/Orbital-style — the loader is
the compositor, the cartridge is the app), the rustlite compiler gained
host-import calls so agent-written Rust can draw, and a subdomain boots
straight into its published cartridge fullscreen.

Added

• DISPLAY framebuffer. A <canvas> "screen" that runs wasm
  cartridges via host_display: cartridges write pixels and the host
  blits them — no DOM, no iframe. Cartridges export frame(t)
  (animated, driven by requestAnimationFrame) or render() (one-shot).
• host_display ABI: clear, set_pixel, fill_rect,
  draw_char / draw_number (hand-rolled 5×7 font: 0-9, A-Z, space,
  + - * / = . ( )), present, width/height, pointer input
  (pointer_x/pointer_y/pointer_down, poll model), and a 64-slot
  integer state_get/state_set register file that persists across
  frames (rustlite has no globals).
• rustlite → display bridge. The compiler now emits wasm host-import
  calls: typecheck resolves display::* against a host-function table;
  codegen builds an import section and offsets local function indices.
  Agent-written rustlite cartridges, compiled in-browser, draw on screen.
• run_cartridge tool. The agent compiles rustlite and runs it
  directly on the display.
• App mode. A subdomain with an app.rl (rustlite source) in OPFS
  boots straight into a chrome-less fullscreen cartridge; ?edit=1
  returns to the workshop.
• Cross-visitor publishing. The compiled cartridge wasm is stored
  on-chain in the registry diamond under
  metadata(tokenId, keccak256("localharness.app.wasm")) (no new facet)
  via a sponsored setMetadata tx. Every visitor — not just the owner's
  device — boots into the published app. Owner-only "publish app
  on-chain" button in admin.
• Stop buttons. A stop control halts a running cartridge's frame
  loop; the send arrow becomes a stop button while an agent turn streams
  and cooperatively cancels it (guarding against concurrent turns).
• Feedback viewer. The feedback modal lists recent on-chain
  FeedbackSubmitted events (newest first, relative timestamps) via
  eth_getLogs — previously feedback could only be submitted.

Fixed

• rustlite multi-local codegen bug. alloc_local double-counted, so
  any function with 2+ locals emitted out-of-range local indices and
  failed to instantiate. Functions with 0-1 locals worked by luck; the
  emit tests never caught it because they only check the wasm header.
• rustlite control-flow as statements. if/match/block
  expressions now work as statements without a trailing ; (like Rust);
  previously only while/loop did.
• Transcript scroll now lands at the latest turn on load (deferred
  past layout/font-swap).
• Terminal-collapse anchor. The terminal rail stays pinned to the
  bottom of the column when the terminal/view panels collapse instead of
  floating to the top.
