Add GitHub Actions CI and Makefile

- Add .github/workflows/ci.yml with jobs for:
  - check: cargo check
  - fmt: formatting verification
  - clippy: linting with warnings as errors
  - test: run all tests
  - doc: documentation generation
  - ci-success: summary job

- Add Makefile with common development commands:
  - make ci: full CI pipeline
  - make test: run tests
  - make fmt/fmt-fix: format checking and fixing
  - make clippy/clippy-fix: linting
  - make doc/doc-open: documentation
  - make quick: fast development checks

- Fix all clippy warnings:
  - Replace manual range contains with (0.0..=1.0).contains()
  - Replace map_or(false, ..) with is_some_and()
  - Add #[allow] for intentional patterns (module_inception, type_complexity)
  - Rename from_iter to collect_from to avoid trait confusion

- Apply rustfmt formatting to all files
