💄 Fix docstrings and clarify filter expression in path namespaces

- Fix 'conten' typo to 'content' in path.cljc docstring
- Fix 'curvle' typo to 'curve' in shape_to_path.cljc docstring
- Replace confusing XOR-style filter with readable
  (contains? #{:line-to :curve-to} ...) in bool.cljc
- Align handler-indices and opposite-index docstrings with
  matching API in path.cljc
