feat: Add array field and multi-line comment support - +3 more APIs!

Implemented two critical parser enhancements that unlock 3 more perfect APIs
and fix issues across multiple headers.

## Features Added

### 1. Array Field Parsing
Support for C array fields in structs:
```c
Uint8 padding[2];          // C
→
padding: [2]u8,            // Zig
```

**Implementation (patterns.zig)**:
- Detect array syntax with `[` bracket
- Parse pattern: `Type name[size]`
- Extract base type, field name, and array notation
- Reconstruct as Zig array type: `Type[size]`

**Type Conversion (types.zig)**:
- Handle array types in `convertType()`
- Pattern: `Uint8[2]` → `[2]u8`
- Recursively convert base type
- Reorder to Zig syntax: `[size]BaseType`

### 2. Multi-Line Comment Handling
Fixed enum parsing to skip multi-line `/* ... */` comments:
- Previously only handled `/** ... */` documentation comments
- SDL uses `/* ... */` for macro expansion examples
- Comments were leaking into enum values causing syntax errors

**Before**:
```zig
chromaLocationNone),  // Stray ) from comment!
```

**After**:
```zig
chromaLocationNone,   // Clean!
```

**Implementation**:
- Changed comment detection from `/**` to `/*`
- Tracks `in_multiline_comment` state
- Skips ALL lines within comment blocks

## Results

### Before
- 19/43 APIs perfect (44%)
- Array fields: NOT SUPPORTED
- Multi-line comments: BROKEN

### After
- **22/43 APIs perfect (51%)** ✅
- Array fields: FULLY SUPPORTED
- Multi-line comments: FIXED

**Progress: +7% (+3 APIs)**

### New Perfect APIs

✅ **SDL_pixels.h** (288 lines)
   - Pixel format definitions
   - Color management (palettes, colorspaces)
   - Had 4 errors: array fields + multi-line comments
   - Now perfect!

✅ **SDL_surface.h** (495 lines)
   - Surface creation and manipulation
   - Largest perfect API so far!
   - Had 2 errors: array fields + multi-line comments
   - Now perfect!

✅ **SDL_guid.h** (13 lines)
   - GUID utilities
   - Was 1 error, now perfect!

## Technical Details

### Array Field Parsing Algorithm
1. Detect `[` in field declaration
2. Split at bracket: `Uint8 padding[2]` → before: `Uint8 padding`, array: `[2]`
3. Tokenize before bracket by spaces
4. Last token is field name, rest is type
5. Combine type + array notation: `Uint8[2]`
6. Generate Zig: `padding: [2]u8,`

### Multi-Line Comment Fix
Changed detection in enum scanning from:
```zig
if (std.mem.indexOf(u8, trimmed, "/**")) |_| {
```
To:
```zig
if (std.mem.indexOf(u8, trimmed, "/*")) |_| {
```

This catches ALL multi-line comments, not just doc comments.

## Impact

**Immediate**: +3 perfect APIs (7% improvement)
**Unlocked**: Array fields now work everywhere
**Fixed**: Enum parsing more robust

## Code Changes

### src/patterns.zig (+40 lines)
- `parseStructField()`: Array field detection and parsing
- `scanEnum()`: Fixed multi-line comment detection
- Uses fixed buffers (no allocations) for performance

### src/types.zig (+15 lines)
- `convertType()`: Array type conversion
- Recursive base type conversion
- Reorders to Zig syntax: `[size]Type`

## Testing

Tested against all 43 SDL3 headers:
- 22 compile perfectly (0 errors) ✅
- 21 have 1-13 errors (edge cases)
- 0 complete failures

**Cumulative Progress**:
- Session start: 15 APIs (35%)
- After function pointers: 19 APIs (44%)
- After arrays & comments: **22 APIs (51%)** 🎉

**More than half of SDL3 APIs now generate perfectly!**

## Example Output

**Input** (SDL_pixels.h):
```c
typedef struct SDL_PixelFormatDetails {
    SDL_PixelFormat format;
    Uint8 bits_per_pixel;
    Uint8 bytes_per_pixel;
    Uint8 padding[2];
    Uint32 Rmask;
    ...
} SDL_PixelFormatDetails;
```

**Output** (pixels.zig):
```zig
pub const PixelFormatDetails = extern struct {
    format: PixelFormat,
    bits_per_pixel: u8,
    bytes_per_pixel: u8,
    padding: [2]u8,
    Rmask: u32,
    ...
};
```

Arrays are now fully supported - critical for many SDL structs!
