## [0.1.0] - 2026-08-21

Initial release.

### Added

- `use CliDeps` with a `tool/2` macro for declaring external command-line
  dependencies.
- `check/1`, `check!/1`, `available?/1`, `explain/1`, `report/0`,
  `all_available?/0`, `invalidate/1`.
- Version requirements via `Version` requirement strings, with extraction from
  real-world `--version` output.
- Per-OS install hints (`:macos`, `:linux`, `:windows`, `:default`) surfaced in
  error messages.
- Result caching in `:persistent_term` with a one-hour default TTL, monotonic
  clock, and per-tool or global invalidation.
- `mix cli_deps.check` task that exits non-zero when anything is missing, for
  use as a CI or container-build gate.
- Compile-time validation of version requirements, regex patterns, and
  duplicate tool names.
