  1. fix(web): dispose idle MCP server instances to prevent process accumu… 

    …lation

In `opencode web` mode, switching projects creates new Instance entries (each
spawning MCP server child processes) that are never cleaned up. Unlike the TUI
which calls shutdown()/disposeAll() on exit, the web command blocks forever
with `await new Promise(() => {})` and never reaches its `server.stop()` call.

This causes unbounded process growth — each project switch leaks ~200MB of MCP
server processes (linear, notion, etc.) that persist for the lifetime of the
web server.

Fix:
- Add signal handlers (SIGINT, SIGTERM, SIGHUP) to the web command that call
  Instance.disposeAll() with a 5s timeout before exiting
- Add idle eviction to Instance: track last access time per directory, sweep
  every 60s, and dispose instances idle for >5 minutes
- Clean up lastAccess bookkeeping in dispose() and disposeAll()

  2. feat(web): embed UI in binary; bypass auth for static routes 

    Build the app during 'bun run script/build.ts' and bundle all dist files
into the binary using Bun's 'with { type: "file" }' import syntax. Falls
back to the existing app.opencode.ai CDN proxy when built with
--skip-embed-web-ui, or when OPENCODE_DISABLE_EMBEDDED_WEB_UI=1.

Also adds --skip-app-build flag to skip the Vite build step when dist is
already fresh.

Auth is bypassed for all non-/v1 paths so the UI can load its own login
prompt before the user has authenticated.

Closes #8549, #6352, #12445
