Syncs words/notes/images from backup locations to project input directory

Preserves generated poems.json files to avoid redundant extraction

#

Issue 8-042: Added configurable image sync from config.lua

Issue 10-014: Migrated from input-sources.json to unified config.lua

Issue 7-003: Added --force flag to skip file preservation

#

The external sync-to-projects script does rm -rf input/, which would delete

the generated files that scripts/update creates. We preserve and restore them

so the freshness check works correctly.

#

Usage: scripts/update-words [--force]

--force: Skip file preservation (regenerate everything from scratch)

Issue 8-059: route the preserve/restore backup through the project's

tmpfs-backed tmp/ symlink rather than a real on-disk temp/ directory.

Issue 10-003b: Config helper functions removed

Image syncing now uses centralized external-sync module via scripts/sync-external-files
