/**
 * decidePhases — the pure phase-gating decision behind `celilo publish`.
 *
 * The module-phase flags (`--skip-modules` / `--modules-only`) exist so
 * the release pipeline can deliver the CLI independently of the module
 * sweep (celilo#1369). Their gating lives in one pure function so the
 * combinations are testable without npm, git or the registry.
