refactor(cli): reorganize commands — add test, alias orchestrate to o, extract shared options

- Add `test` / `t` command mirroring unity-test-runner (EditMode, PlayMode, All,
  code coverage, test filters)
- Add `o` short alias for `orchestrate` command
- Extract shared option builders (project, docker, android, orchestrator) to
  eliminate duplication across build/test/orchestrate
- Make `build` local-only — remove --provider-strategy (use `orchestrate` for
  remote builds)
- Absorb `cache` command into `status` (--cache-dir flag) — remove standalone
  cache command that was half-implemented
- Fix `list-worfklow` typo in internal CLI → `list-workflow`
- Add test-related fields to CliArguments input mapper
- Update all unit and integration tests (64 passing)

Command structure is now:
  game-ci build          Local build (Docker/macOS)
  game-ci test / t       Run Unity tests
  game-ci orchestrate / o  Remote build (AWS/K8s/etc)
  game-ci activate       License validation
  game-ci status         Project info + cache status
  game-ci version        Version info
  game-ci update         Self-update
