fix: address review comments - preserve tab delimiters in List and fix transitive needs cross-namespace resolution

1. exec.go List(): Filter empty lines without TrimSpace-ing non-empty
   lines, preserving trailing tab separators from helm list output.

2. state.go collectNeedsWithTransitives(): Resolve transitives by full
   ReleaseToID matching (via ID→ReleaseSpec map) instead of name-based
   matching, avoiding cross-namespace ambiguity when multiple releases
   share the same name.
