feat: Quickstart and client for Plain JS Script Tags (#4161)

# Description of Changes

The PR implements the following updates:

- Create a quickstart guide and client support for using SpacetimeDB
directly in browser with script tags
- A template to easily work with/test the implementation and get started
with script tags

The bundle is served via
`https://unpkg.com/spacetimedb@latest/dist/browser.bundle.js`, which
only works after the package is published to npm, therefore to test
locally we can use the `browser-ts` template and local bundle:
1. Build local bundle
```
cd crates/bindings-typescript
pnpm install
pnpm build
```
2. Use local bundle built in template`index.html` (swap the URL from
`unpkg`)
```diff
- <script src="https://unpkg.com/spacetimedb@latest/dist/browser.bundle.js"></script>
+ <script src="../../crates/bindings-typescript/dist/browser.bundle.js"></script>
```
3. Open `browser-ts/index.html` directly in browser along with
`spacetime start` + publish the module `spacetime publish --project-path
spacetimedb browser-ts`

+Get a SpacetimeDB app running in the browser with inline JavaScript.

+## Prerequisites

+- [Node.js](https://nodejs.org/) 18+ installed
+- [SpacetimeDB CLI](https://spacetimedb.com/install) installed
+

+
+<StepByStep>
+  <Step title="Create your project">
+    <StepText>
+      Run the `spacetime dev` command to create a new project with a TypeScript SpacetimeDB module.
+
+      This will start the local SpacetimeDB server, publish your module, and generate TypeScript client bindings.
+    </StepText>
+    <StepCode>
+```bash
+spacetime dev --template browser-ts my-spacetime-app
+```
+    </StepCode>
+  </Step>
+
+  <Step title="Build the client bindings">
+    <StepText>
+      The generated TypeScript bindings need to be bundled into a JavaScript file that can be loaded in the browser via a script tag.
+    </StepText>
+    <StepCode>
+```bash
+cd my-spacetime-app
+npm install
+npm run build
+```
+    </StepCode>
+  </Step>
+
+  <Step title="Open in browser">
+    <StepText>
+      Open `index.html` directly in your browser. The app connects to SpacetimeDB and displays data in real-time.
+
+      The JavaScript code runs inline in a script tag, using the bundled `DbConnection` class.
+    </StepText>
+    <StepCode>
+```html
+<!-- Load the bundled bindings -->
+<script src="dist/bindings.iife.js"></script>
+
+<script>
+  const conn = DbConnection.builder()
+    .withUri('ws://localhost:3000')
+    .withModuleName('my-spacetime-app')
+    .withToken(localStorage.getItem('auth_token'))
+    .onConnect((conn, identity, token) => {
+      localStorage.setItem('auth_token', token);
+      console.log('Connected:', identity.toHexString());
+
+      // Subscribe to tables
+      conn.subscriptionBuilder()
+        .onApplied(() => {
+          for (const person of conn.db.person.iter()) {
+            console.log(person.name);
+          }
+        })
+        .subscribe(['SELECT * FROM person']);
+    })
+    .build();
+</script>
+```
+    </StepCode>
+  </Step>
+
+  <Step title="Call reducers">
+    <StepText>
+      Reducers are functions that modify data — they're the only way to write to the database.
+    </StepText>
+    <StepCode>
+```javascript
+// Call a reducer with named arguments
+conn.reducers.add({ name: 'Alice' });
+```
+    </StepCode>
+  </Step>
+
+  <Step title="React to changes">
+    <StepText>
+      Register callbacks to update your UI when data changes.
+    </StepText>
+    <StepCode>
+```javascript
+conn.db.person.onInsert((ctx, person) => {
+  console.log('New person:', person.name);
+});
+
+conn.db.person.onDelete((ctx, person) => {
+  console.log('Removed:', person.name);
+});
