fix(SoundDodge): PEP 562 延迟加载 + CI 预装 patched soundcard (#207)

* fix(SoundDodge): PEP 562 延迟加载 + CI 预装 patched soundcard

- __init__.py: 用 __getattr__ 延迟导入 Ear/Dodger，避免 import custom
  时 module-level import soundcard 触发 cffi.dlopen('ole32') 崩溃
- install.yml: CI 打包时将 soundcard 预装进 embedded Python 并 patch
  mediafoundation.py 中 ole32 → ole32.dll，从源头修复 find_library 问题

* fix(ci): soundcard patch 前校验目标字符串存在，防止静默回归

replace() 找不到目标时静默成功，若 soundcard 未来改动
mediafoundation.py 则 ole32 崩溃会悄悄回来。加显式检查让
CI 硬失败。

* chore(SoundTrigger): remove blank lines inside if blocks for Black compliance

* fix(ci): use heredoc for soundcard patch to fix YAML indentation
