refactor: restructure bastion as pnpm monorepo (@lab/shared, @lab/bastion, @lab/cli)

- Split into 3 workspace packages: shared (types/constants), bastion (server), cli
- CLI binary renamed from "bastion" to "lab"
- Cross-package imports via @lab/shared and @lab/bastion workspace references
- Extracted BastionConfig, BastionState, HardwareInfo types into @lab/shared
- Added APP_NAME/APP_VERSION constants
- tsconfig.base.json with project references for build ordering
- Root workspace scripts: build, test, typecheck, clean
