Pass --key-delay 8 to ydotool type instead of relying on the default
(12-20ms). This makes text injection ~3x faster while keeping key-delay
above zero to avoid the Shift-leak bug where capital letters corrupt
following characters.
The delay is configurable via VOCALINUX_YDOTOOL_KEY_DELAY env var.
Note: --key-hold flag from the original issue does not exist in standard
ydotool (verified against official man page and v1.0.4 source).
Fixes#482
