v0.6.5

Adjustments for loop mode behaviour for better integration with layer shell surface.

Bugfixes

• hide child process' stderr when loop mode is in use, so it won't interfere with operation when otter stays opened.
• fix unbind_proc regression when handling more complicated bash commands.
• fix default config app launcher not ordering alphabetically.
• streamlined codes with cleaner functions.

Other

• add chatgpt prompt module to default config to demonstrate otter's capability of more complicated scripting.
• add tutorials in readme for running otter in wayland layer shell surface
