/**
 * Tests for `--minimal` install profile (#2762).
 *
 * Verifies:
 *   1. The install-profiles allowlist contains exactly the documented core
 *      main-loop skills.
 *   2. stageSkillsForMode() filters source dir entries to the allowlist when
 *      mode === 'minimal' and is a no-op for mode === 'full'.
 *   3. Filtering is by basename (mirrors how copyCommandsAs*Skills derives
 *      skill names).
 *   4. shouldInstallSkill() agrees with stageSkillsForMode().
 *
 * Note: end-to-end install tests (spawning bin/install.js with --minimal) are
 * intentionally out of scope here — they require a fully-mocked runtime config
 * dir which would duplicate antigravity-install.test.cjs scaffolding. The unit
 * tests below pin the allowlist contract; the dispatch sites in install.js
 * call stageSkillsForMode unconditionally so any breakage there shows up as
 * a stage_dir/source_dir mismatch covered by these tests.
