Aaron SinclairandClaude ddd2c03a9d Implement RitzMain() convention and Main.wasm standard ...

**Convention: RitzMain() entry point**
Every Ritz file now requires a `@component def RitzMain()` as the entry point.
This provides a consistent, predictable entry point for all applications.

**Universal Main.wasm output**
Build system now always outputs Main.wasm instead of ComponentName.wasm.
This means every example uses the exact same HTML boilerplate!

**Changes:**

**Codegen (llvm_codegen_signals.py):**
- Check for RitzMain component at generation time
- Error if RitzMain not found: "No RitzMain component found!"
- Always call `render_RitzMain()` from main() entry point
- Fix: Scope reactive text nodes to components (`@reactive_text_ComponentName_N_node`)
  - Prevents global name collisions when multiple components have reactive text

**Build (build.py):**
- Output Main.wasm in same directory as source file
- Output Main.ll (LLVM IR) for inspection
- Convention over configuration!

**Loader (ritz-runtime.js):**
- Auto-detect component name from WASM filename
- `new RitzLoader().load('Main.wasm')` - no second parameter needed!
- Component name used only for status messages

**Template (examples/template.html):**
- Minimal boilerplate - literally 25 lines
- Just copy and change nothing!
- Loads Main.wasm - works for every example

**Styles (examples/runtime/styles.css):**
- Shared styles for all examples
- Clean, modern defaults
- App container, buttons, inputs, typography

**Example (HighFive):**
```python
@component
def HighFive():
    # ... component logic

@component
def RitzMain():
    """Entry point - required!"""
    yield HighFive()
```

**Result:**
✅ Every example: copy template.html, change nothing
✅ Every example: builds to Main.wasm
✅ Consistent entry point: RitzMain()
✅ No more component name boilerplate
