Move all tests under test/ mirroring src layout

[rafaeelricco]

Motivation

Tests were co-located next to source files under src/, while helpers and smoke tests already lived in test/. This PR consolidates every test under test/ with a layout that mirrors src/, so test discovery and tooling config stay in one place.

What's New

Test layout

• Move 18 src/**/*.test.ts files into test/ (cli/, domain/, infra/, libs/)
• Relocate smoke coverage to test/cli/smoke.test.ts

Tooling

• Restrict Vitest discovery to test/**/*.test.ts
• Add @test/ alias for shared helpers such as run-future and temp-git-repo
• Include test/**/* in TypeScript typecheck and ESLint coverage

Test fixes

• Standardize helper imports on @test/helpers/*
• Fix typecheck issues surfaced by including tests in tsc (e.g. Future.resolve(undefined), Success/Failure narrowing)

Testing & Feedback

• Confirm pnpm test still reports 20 files / 73 tests
• Confirm pnpm typecheck and pnpm run lint:ci pass
• Spot-check that CLI smoke tests still resolve dist/index.js from the new path

Critical correctness scan

Reviewed PR #27 (19ffd65) and the parent Vitest refactor (#26, 3f777b8). Scope is test layout, path aliases, and config updates only; no src/ production logic changed in this PR.

Checks run: pnpm test (69 passed), pnpm typecheck, pnpm build.

Findings: No critical correctness issues. The prior import-time CONFIG_DIR/CONFIG_FILE hazard from #26 is already addressed via lazy configDir()/configFile() plus per-test COMMIT_TOOLS_HOME in test/setup.ts.

Below critical bar (not actionable here): Bare commit-tools now defaults to generate instead of help (#26, documented in --help).
