#
# Prepares bundled resources for distribution.
#
# This script copies resources that should be bundled with Warp into a
# destination directory. It is used by macOS and Linux build scripts.
#
# Usage:
#   prepare_bundled_resources <destination_directory> [channel] [cargo_profile]
#
# Arguments:
#   destination_directory:  The directory where resources should be installed.
#                           Resources will be copied to subdirectories within
#                           this path (e.g., $DEST_DIR/skills).
#   channel:                (Optional) Release channel (local, dev, preview,
#                           stable). Used to include channel-gated skills.
#   cargo_profile:          (Optional) Cargo build profile to use when
#                           generating the settings schema. Reusing the same
#                           profile as the main build avoids recompiling deps.
#
# Environment variables:
#   SKIP_SETTINGS_SCHEMA: Set to "1" to skip generating the JSON settings
#                         schema. By default the schema is always generated
#                         so that production bundles never accidentally omit it.
#   SETTINGS_SCHEMA_CACHE: Path to a cache file for the generated schema.
#                          When set, the first invocation generates the schema
#                          and saves a copy to this path; subsequent invocations
#                          copy from the cache instead of regenerating. This
#                          avoids redundant compilations when bundling multiple
#                          package formats for the same channel.
