Disable tmux Terminal Features with @ Suffix

Disable specific tmux terminal features using the @ suffix. This prevents conflicts when using platform-specific tools (like clip.exe for WSL2 clipboard).

# Disable OSC 52 clipboard for xterm-compatible terminals
set -as terminal-features 'xterm*:clipboard@'

The @ suffix explicitly disables the feature. Use set -as (append to server option) rather than indexed assignment to avoid pollution on config reload.

Common features to disable:

• clipboard@ - OSC 52 clipboard (when using platform-specific clipboard tools)
• hyperlinks@ - OSC 8 hyperlinks
• title@ - Window title setting

To see current terminal features:

tmux show -s terminal-features
