fix(hub): rebase agent config folders onto main and sync lockfile

Rebased feat/agent-config-folder-tree onto current main, keeping cursor
invalidation (not session archive) and requireFolder helpers. Regenerated
package-lock so npm ci finds @emnapi/*; tighten session-cursor test assert
for missing claudeSessionId key.
