harn-lint 0.10.64

Linter for the Harn programming language
Documentation
harn-lint-0.10.64 has been yanked.

Harn's lint crate. The public surface is intentionally narrow: a handful of lint_* entry points, the diagnostic and options types, and a couple of small utility functions reused by other crates. All walk state, rule dispatch, and source-aware rule implementations live in sibling modules.
