Subject: [PATCH] fix(cli): catch output directory creation errors in render

mkdirSync for the render output path was not wrapped in try-catch,
exposing a raw Node.js EACCES stack trace when the path was invalid
or permissions were denied.

Reproducer:
  npx hyperframes render --output /root/nope/output.mp4
  # Was: raw "Error: EACCES: permission denied" with stack trace
  # Now: clean "Cannot create output directory" error box
