v1.0.1

A performance + robustness release. No public API changes.

Performance

• Node-set predicates (a location path, filter, or union — e.g.
  self::input | self::textarea | self::select) are now evaluated by
  existence: their truth is decided by short-circuit without materializing a
  node-set. A self::a | self::b | self::c predicate collapses to an OR of
  per-arm name tests on the context node. The union-in-predicate query is ~2×
  faster and the field-by-label query ~1.5×; scaling stays linear.

Correctness

• A malformed union predicate with a non-node-set arm (e.g. a | count(b))
  again raises the XPath type error it should, instead of being silently coerced
  to a boolean by the existence optimization.

Maintenance

• Add Dependabot for the GitHub Actions workflows; bump actions/setup-node and
  actions/checkout to v6.
