xiaoju 1d08c1bf4d refactor: reorganize CLI E2E tests into tests/ by scenario
Move 4 monolithic test files (cli.test.ts, e2e.test.ts, template.test.ts,
var.test.ts) from src/ into tests/ directory, split by scenario:

  tests/helpers.ts           - shared utilities (envValue, stripVolatile)
  tests/put-get-has.test.ts  - basic CAS storage operations
  tests/verify-refs-walk.test.ts - graph traversal
  tests/schema-validation.test.ts - Issue #50 schema validation
  tests/alias.test.ts        - @ alias resolution
  tests/variable.test.ts     - var set/get/delete/list/tag
  tests/template.test.ts     - template set/get/list/delete
  tests/render.test.ts       - render + render -p
  tests/pipe.test.ts         - pipe composition + stdin input
  tests/gc.test.ts           - garbage collection
  tests/edge-cases.test.ts   - help, --store, error paths

All 516 tests pass (159 CLI + 357 core/fs).
