Fix enum34 error by excluding it in PyInstaller spec

The previous approach of uninstalling enum34 before PyInstaller didn't
work because 'uv run' re-syncs dependencies. The proper solution is to
exclude enum34 directly in the PyInstaller spec file.

Changes:
- Added hooks/hook-enum34.py: Custom PyInstaller hook to exclude enum34
- Updated local-transcription.spec:
  - Added 'hooks' to hookspath
  - Added 'enum34' to excludes list
- Updated build.sh and build.bat:
  - Removed enum34 uninstall step (no longer needed)
  - Added comment explaining enum34 is excluded in spec

Why this works:
- PyInstaller's excludes list prevents enum34 from being bundled
- The custom hook provides documentation and explicit exclusion
- enum34 can remain installed in venv (won't break anything)
- Works regardless of 'uv run' re-syncing dependencies

enum34 is an obsolete Python 2.7/3.3 backport that's incompatible with
PyInstaller and unnecessary on Python 3.4+ (enum is in stdlib).
