Add Tailwind HTML embed build

[bholmesdev]

Closes #55

Summary:

• add build:html-embed for compiling Tailwind v4 utilities into local HTML embed artifacts
• add a playground tailwind-card.html source and generated tailwind-card.dist.html embed
• document the source/output convention for agents and contributors

Validation:

• pnpm --filter @hubble.md/desktop build:html-embed apps/desktop/fixtures/playground/tailwind-card.html
• pnpm check
• pnpm build:desktop
• git diff --check

E2E:

• Not run; this is build tooling plus a static playground embed artifact. The generated .dist.html was smoke-built and linked from the playground note.

Notes:

• Build logs include the existing apps/web Node 22.x engine warning under the current runtime.

Closing this for now — the Tailwind HTML embed build path isn't needed at the moment, and I'm not happy enough with the implementation to land it.

We can revisit if/when we add a larger build pipeline for apps.
