## Analysis Details

### Changes Reviewed

The `package.json` diff is limited entirely to the `scripts` section:

1. **`test:all`** — appended `npm run test:tmux && npm run test:tmux:integration` to the chain
2. **`test:implementations`** — added `--exclude='**/tmux/**'` to avoid double-running tmux tests
3. **`test:tmux`** (new) — runs `tests/unit/implementations/tmux` with standard 2GB memory limit
4. **`test:tmux:integration`** (new) — runs `tests/integration/tmux` with standard 2GB memory limit
5. **`test:integration`** — added `--exclude='**/tmux/**'` to avoid double-running tmux tests

### No Dependency Changes

- **Zero new production dependencies** added. The tmux abstraction layer uses only Node.js builtins (`fs`, `path`, `child_process`, `os`) and internal project modules.
- **Zero new devDependencies** added. Tests use only the existing `vitest` devDependency.
- **No version bumps** to any existing dependency.
- **No lock file changes** (`package-lock.json` is unmodified).
- `npm ls --depth=0` reports zero missing or extraneous packages.

### Positive Observations

- The decision to use native Node.js APIs (`child_process.exec` for tmux commands, `fs.watch` for file monitoring, `fs.readFile`/`fs.writeFile` for IPC) rather than pulling in third-party tmux or process management libraries is sound. It minimizes the attack surface, avoids transitive dependency risk, and keeps the bundle lean.
- New test scripts follow the established project pattern: 2GB memory limit via `NODE_OPTIONS`, `--no-file-parallelism`, and proper isolation via `--exclude` flags to prevent double-running.
