Add Sony vendor theme to VendorThemes for automatic PlayStation labeling

[Copilot]

Describe your changes

Adds Sony (vendor ID 054c) to VendorThemes array alongside existing Nintendo and Microsoft entries. Unrecognized Sony controllers now automatically receive PlayStation button schema.

Changes:

• Added GameInputSchema.Ragdoll vendor theme for Sony devices in src/gameinput.js
• Added vendor matching test coverage in src/vendor-theme-matching.test.js

Technical decision: Uses Ragdoll (modern schema with "options"/"share" center buttons) rather than RagdollOld (legacy "start"/"select"). DualShock 4 and DualSense use Ragdoll; DualShock 3 uses RagdollOld but has explicit model entries. Choice documented in code comments.

// Before: Only Nintendo and Microsoft
VendorThemes: [
    new GameInputModel(GameInputSchema.Plumber, 'generic', '057e-0000-Nintendo Device'),
    new GameInputModel(GameInputSchema.Hedgehog, 'xboxone', '045e-0000-Microsoft Device')
]

// After: Sony included
VendorThemes: [
    new GameInputModel(GameInputSchema.Plumber, 'generic', '057e-0000-Nintendo Device'),
    new GameInputModel(GameInputSchema.Hedgehog, 'xboxone', '045e-0000-Microsoft Device'),
    new GameInputModel(GameInputSchema.Ragdoll, 'generic', '054c-0000-Sony Device')
]

Describe your testing

• All 2154 existing tests pass
• New test validates vendor ID matching (054c) and schema assignment (Ragdoll)
• Verified matching across Firefox format (054c-0ce6-Device), Chrome format (Device (Vendor: 054c Product: 0ce6)), and STANDARD GAMEPAD variants
• Manual verification confirms PlayStation symbols (△ ✕ ◯ □) mapped correctly

<issue_title>Add Sony vendor theme to VendorThemes for automatic PlayStation labeling</issue_title>
<issue_description>## Problem
Currently VendorThemes includes Nintendo (057e) and Microsoft (045e) but is missing Sony (054c). This means unrecognized PlayStation controllers don't get proper button labels.

Current VendorThemes

// src/gameinput.js - VendorThemes array
static VendorThemes = [
    // Nintendo devices
    new GameInputModel(
        GameInputSchema.Plumber,
        'generic',
        '057e-0000-Nintendo Device'
    ),
    // Microsoft devices
    new GameInputModel(
        GameInputSchema.Hedgehog,
        'generic',
        '045e-0000-Microsoft Device'
    )
    // ❌ Sony is missing!
]

Proposed Addition

static VendorThemes = [
    // Nintendo devices (vendor ID 057e)
    new GameInputModel(
        GameInputSchema.Plumber,
        'generic',
        '057e-0000-Nintendo Device'
    ),
    // Microsoft devices (vendor ID 045e)
    new GameInputModel(
        GameInputSchema.Hedgehog,
        'generic',
        '045e-0000-Microsoft Device'
    ),
    // Sony devices (vendor ID 054c)
    new GameInputModel(
        GameInputSchema.Ragdoll,
        'generic',
        '054c-0000-Sony Device'
    )
]

Benefits

• DualShock 3, DualShock 4, DualSense controllers automatically get PlayStation symbols (△ ✕ ◯ □)
• Consistent vendor theme handling across major manufacturers
• Better out-of-box experience for PlayStation users

Testing

• Test with DualShock 3 USB/Bluetooth
• Test with DualShock 4 USB/Bluetooth
• Test with DualSense USB/Bluetooth
• Verify vendor ID matching logic in matchesVendor()

Important

We should apply the correct "Ragdoll" vs "RagdollOld" schema. If we cannot properly determine which is appropriate, we should simply document that.</issue_description>
