grant-plugin-permissions.sh

#!/usr/bin/env bash
#
# Pre-grant Zellij permissions for the lince-dashboard plugin.
#
# Zellij stores granted permissions in ~/.cache/zellij/permissions.kdl.
# On a fresh install, the plugin shows a permission dialog that the user must
# accept. If the dialog is missed or doesn't appear, the plugin runs without
# permissions and panics on any privileged API call.
#
# This script creates the permissions.kdl cache file so the plugin starts
# with all required permissions already granted.
#
# Usage:
#   bash grant-plugin-permissions.sh           # grant permissions
#   bash grant-plugin-permissions.sh --show    # show current permissions
#   bash grant-plugin-permissions.sh --reset   # remove cached permissions
#
