Add one-liner install script and GitHub release workflow

- install.sh: Downloads pre-built binary for platform (Linux/macOS x86_64/aarch64)
- .github/workflows/release.yml: Builds and uploads binaries on version tags
- README.md: Add curl install method, fix typos, add --root-label to CLI ref

Usage:
  curl -fsSL https://raw.githubusercontent.com/rawwerks/dirpack/master/install.sh | bash

Release process:
  git tag v0.2.1 && git push --tags

 dirpack creates compressed directory representations that fit within token/byte budgets. Unlike other tools, it uses **progressive disclosure**—including structure first, then signatures, then content—stopping exactly when the budget is exhausted.
 
-dirpack was inpired by [recent research from Jude Gao at Vercel](https://vercel.com/blog/agents-md-outperforms-skills-in-our-agent-evals), which suggests that putting a "compressed" index of the directory directly inside `AGENTS.md` out performs the "progressive disclore" strategy recommended by [Agent Skills](https://github.com/agentskills/agentskills)
