# Plugin Package Build Script
#
# This script orchestrates the complete build process for the Nori plugin package.
# It compiles TypeScript, resolves path aliases, bundles paid skills, and prepares
# all configuration files for installation.
#
# Build Pipeline:
# 1. Clean build directory
# 2. TypeScript compilation (tsc)
# 3. Path alias resolution (tsc-alias)
# 4. Paid skills bundling (esbuild)
# 5. File permissions setup
# 6. Configuration file copying
# 7. Version substitution

# - Produces single-file executables

# backwards compatibility during auto-updates. When users auto-update from
# older versions (e.g., 18.x -> 19.x), Claude Code caches hook paths at session
# start. The old paths point to features/hooks/config/ but new versions use
# features/claude-code/hooks/config/. By copying hooks to both locations, old
# sessions can still find working hooks when they end after an update.
#
# This can be removed after a few major versions when most users have updated.
