* feat(cli): deduplicate identical script lockfiles into one per language
* test: pin shared lockfile path classification
* fix(cli): never delete a lockfile the dedup plan also writes
* fix(cli): plan lockfile dedup from the whole tree, not the sync scope
* fix(cli): keep dedup out of dry runs and stop hiding scripts from its scan
* test: pin which files the shared-lock scan counts as readers
* fix(cli): validate shared-lock refs and let the majority keep its file
* fix(cli): snapshot shared-lock ownership before regeneration moves it
* fix(cli): address dedup review nits (dry-run push, json shape, scan scope)
* refactor(cli): put shared lockfiles in a top-level locks/ directory
* fix(cli): claim only the shared lock names windmill writes, and only when on
* fix(cli): read the lock field itself, and count only scripts sync reads
* fix(cli): parse metadata by its real format and lint from the sync root
* fix(cli): never re-hash a script whose generation failed
* fix(cli): share sync's walk exclusions and fail closed on unreadable dirs
* fix(cli): keep a lockfile the metadata on disk still references
* fix(cli): decide a lock is unread from the metadata field sync reads
* refactor(cli): name shared lockfiles after the dependency file they resolve
* fix(cli): carry shared lockfiles a narrowed sync cannot speak for
* fix(cli): move a shared lockfile when its dependency file moved, not on a head count
* fix(cli): let the many correct a shared lockfile a lone variant planted
* fix(cli): read why a lock differs from the stamp the worker writes into it
* fix(cli): let an agreeing majority speak whatever the stamps say
* docs(cli): count the disjuncts the comment introduces
* fix(cli): keep a private lock for any script the worker locks differently
* fix(cli): match annotations by the worker's own names, not by shape
* fix(cli): recognize the py: interpreter pin the macro does not cover
* fix(cli): let the map speak for dependency-file deletions
* perf(cli): group lock entries without rebuilding the group per insert
* fix(cli): defer shared-lock deletions until the metadata has settled
* fix(cli): decide shared-lock readers by the lock field, failing closed
* fix(cli): read folded lock refs and keep locks read by unparseable metadata
* refactor(cli): one shared-lock reader scan, shared by the pull and push paths
* fix(cli): keep nested dependency set names out of shared lockfiles
* fix(cli): drop a shared-lock scan gate that no real repo took
