fix(cli): share Vault-relative path exclusions

Apply watcher and logical-target exclusions within the selected Vault so
hidden or database-like parent directories do not suppress monitoring.
Protect primary, previous, and view databases, and provide a runtime opt-in
for ordinary database-like directories without changing database ownership.

Cover hidden roots, symlink restarts, exclusion parity, and encrypted
CouchDB create, modify, and delete operations with regression tests.
