Fix Windows CUDA dependency resolution marker mismatch

[Copilot]

uv dependency resolution failed on Windows because required-environments specified platform_machine == 'AMD64' but torch dependencies only used sys_platform == 'win32'.

Changes

• Dependencies: Added platform_machine == 'AMD64' marker to Windows torch/torchvision/torchaudio dependencies
• Sources: Updated [tool.uv.sources] markers from sys_platform == 'win32' to (sys_platform == 'win32' and platform_machine == 'AMD64')

# Before
"torch==2.7.1+cu128; sys_platform == 'win32'",

# After  
"torch==2.7.1+cu128; sys_platform == 'win32' and platform_machine == 'AMD64'",

This aligns dependency markers with the environment specification, allowing uv to correctly resolve torch packages for Windows AMD64.

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• astral.sh
  • Triggering command: /usr/bin/curl curl -LsSf REDACTED (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)

    fix: prevent stale src_audio from leaking into text2music (Custom) mode (#584)

    Custom/text2music mode operates exclusively on LM-generated audio codes
    or user-provided LM Codes Hints. It should never use src_audio.

    When switching from Remix/Repaint back to Custom, the Gradio UI hides
    the src_audio widget but does not clear its value. This caused the
    residual source audio to be processed and affect duration calculation
    and padding in text2music generation.

    Fix applied at three defence layers:
    - results_handlers.py: clear src_audio before building GenerationParams
    - inference.py: pass None to handler for text2music task_type
    - handler.py: skip process_src_audio when task_type is text2music

    Added 13...

@copilot I need broader environmental compatibility. Won’t such superficial changes lead to incompatibility with many other devices?
