Enable browser curl requests to any HTTPS host

The browser shell currently rejects network commands. This enables `curl` from Shell and Pi's bash tool for any HTTPS host, using browser `fetch` without a backend or proxy. For example, Pi can fetch a raw GitHub Gist or download JSON and inspect it with `jq`.

GET, HEAD, and POST are supported, with an 8-second deadline, a 1 MiB response cap, and cancellation through Stop. Browser CORS still applies; cookies are omitted and redirects require the final URL. Model/tool instructions, the shell footer, setup copy, and HTTP help explain this behavior.

This follows the repository's prebuilt-static-app layout: it replaces the main and agent-worker bundles, removes their superseded versions, adds the help page, and updates the README. The JavaScript bundles are byte-identical to the tested duplicate. The HTML/help retain this Space's identity, and stale townbox metadata/direct-app links now point to victor.

Validation:
- 22 unit tests and the production build passed.
- 17 real-browser shell checks passed on the [test Space](https://huggingface.co/spaces/Mike0021/MiniCPM5-2B-WebGPU-Pi-HTTP), including previously unlisted hosts, raw Gists, GET/HEAD/POST, CORS/redirect errors, timeout, cancellation, and persistence.
- Actual MiniCPM5-2B fetched a public Gist and correctly described it in 7.4 seconds.
- A final smoke test applied these exact PR files over the current victor snapshot: raw Gist fetch, non-HTTPS rejection, help page, and canonical metadata passed with no page errors.

Reviewable [source and tests](https://huggingface.co/spaces/Mike0021/MiniCPM5-2B-WebGPU-Pi-HTTP/tree/1b0b7301591a12ab1aa1b6b9fe1c6e1042c4546a/app): the transport is `src/browser-http.mjs`, wired through `src/workspace.mjs` and `src/agent.worker.mjs`. The [validation report](https://huggingface.co/spaces/Mike0021/MiniCPM5-2B-WebGPU-Pi-HTTP/blob/1b0b7301591a12ab1aa1b6b9fe1c6e1042c4546a/validation/REPORT.md) records both current results and earlier model limitations (duplicate POSTs and excessive retries). These checks establish the integration, not general agent reliability.

 Send your first message. If the complete verified model is already cached in this browser, Pi restores it and sends your message automatically, without a confirmation dialog. Otherwise, a **Load model & send** dialog explains the download. Confirming closes the dialog and shows progress in the top bar, then sends your message automatically. Cancel or Stop keeps your unsent draft; loading errors offer a retry. If the cache is incomplete or has changed, downloading missing files requires confirmation. You can also click **Load model** ahead of time. The first download is about **1.84 GB**; files are SHA-256 verified and cached in OPFS. The loader uses bounded byte ranges, retries, cancellation, and separate download / GPU setup / warm-up phases. Chat and virtual files are saved in IndexedDB on this site. Cached weights can be reused after reloading. The entire workspace uses a dark theme.

 Requires WebGPU with FP16 (`shader-f16`) in a browser worker, OPFS, and sufficient storage and device memory. There is an 8,192-token prompt-plus-output budget, up to 2,048 generated tokens per model call, and a 12-turn limit per request. Desktop and narrow-screen layouts are included. Physical Android/iOS devices have not been tested.

 The top bar shows the model, its load status, and a live token-speed sparkline labeled **WebGPU** for inference or **JavaScript** for tool execution. Speed is measured from generated tokens, including thinking; prompt processing and tool execution have their own statuses. The chart clears when generation stops. Successful file reads open the corresponding workspace file while preserving unsaved edits. Common file types have Seti icons. The shell includes live Bash syntax coloring, multiline commands, session history, colored errors/exit states, and a resizable output area. Panels use background shading and rounded corners sized to their nested spacing throughout the dark workspace.
 
 The terminal uses Pi's dark palette and native message/editor padding. Recent checks cover seven viewport sizes, Unicode alignment, long tool output, a simulated 60-turn transcript, twelve keyboard interactions, five actual-model workflows, and a ten-turn conversation with twelve tool results. Mobile sizes were simulated on desktop Chromium.
 
+## HTTP requests
+
+Use `curl` in Shell or ask Pi to fetch a URL. Requests go directly from the browser to the destination, with no proxy or backend. Any HTTPS host is allowed; the destination must permit browser access through CORS. Inference remains local.
+
+```bash
+curl -fsS https://jsonplaceholder.typicode.com/todos/1 -o todo.json
+jq '{id, title, completed}' todo.json
+```
+
+GET, HEAD, and POST are supported. Requests have an 8-second deadline and a 1 MiB response limit; Stop cancels an active request. Browser cookies are omitted, and credentials embedded in URLs are rejected. Redirects require the final HTTPS URL directly. Use `set -o pipefail` before pipelines so download failures are preserved. See [HTTP help](http-help.html) for examples and details.
