SimpleCast 0.9.0-beta.14

SimpleCast 0.9.0 beta 14

Beta 14 fixes sound-test metering and makes the inactive optional program
source easier to understand.

Fixes

• The VU meters now follow the actual captured and mixed signal throughout
  Test my sound.
• The live input meter resumes before the automatic processed-preview playback.
• When Program audio is set to None, its volume row explicitly says
  off, the value reads Off, and the slider and reset button are visibly
  muted and disabled.
• A saved program-volume setting returns unchanged when a program is selected
  again.

Verification

• All 85 automated tests pass.
• A real Windows WASAPI test using a Behringer X-AIR recording device and Chrome
  program capture produced 200 live VU callbacks over two seconds at 48 kHz
  stereo.

The Windows beta artifacts are intentionally unsigned, so Windows may show a
SmartScreen or Smart App Control warning.
