Add Homebrew tap and Scoop bucket for package manager support

Start with .goreleaser.yaml and commit 9c13cd4 to review the removed Homebrew and Scoop sections, then inspect README.md's current installation instructions. Create the two repositories, restore the release configuration, and verify that a subsequent release populates both package-manager repositories as described.

Context

Currently, users install via:

• Direct download from GitHub releases
• curl one-liners (Linux/macOS)
• PowerShell one-liner (Windows)
• go install

All methods work fine. This issue is for future consideration when there are more users who might prefer package managers.

What Are These?

Homebrew Tap

Custom Homebrew repository containing formulas (installation recipes).

User experience:

brew install felixisaac/tap/claude-code-sync
brew upgrade claude-code-sync

Scoop Bucket

Custom Scoop repository containing JSON manifests.

User experience:

scoop bucket add felixisaac https://github.com/felixisaac/scoop-bucket
scoop install claude-code-sync
scoop update claude-code-sync

---

Benefits

✅ Slightly easier for users who prefer package managers
✅ Auto-discovery via brew search / scoop search
✅ goreleaser auto-updates them on each release

Downsides

❌ Two more repos to maintain
❌ Adds complexity to release process
❌ Current install methods already work well

How to Implement (when ready)

1. Create Homebrew Tap Repo

Create repo manually at: https://github.com/new

• Name: homebrew-tap
• Description: Homebrew formulae for claude-code-sync and other tools
• Public repo

2. Create Scoop Bucket Repo

Create repo manually at: https://github.com/new

• Name: scoop-bucket
• Description: Scoop manifests for claude-code-sync and other tools
• Public repo

3. Update .goreleaser.yaml

Add these sections back (they were removed in commit 9c13cd4):

brews:
  - repository:
      owner: felixisaac
      name: homebrew-tap
    directory: Formula
    homepage: https://github.com/felixisaac/claude-code-sync
    description: Sync Claude Code configs across machines via GitHub with age encryption
    license: MIT
    install: |
      bin.install "claude-code-sync"
    test: |
      system "#{bin}/claude-code-sync", "version"

scoops:
  - repository:
      owner: felixisaac
      name: scoop-bucket
    homepage: https://github.com/felixisaac/claude-code-sync
    description: Sync Claude Code configs across machines via GitHub with age encryption
    license: MIT

4. Update README.md

Add installation sections for Homebrew and Scoop.

5. Test

After next release, goreleaser will automatically populate both repos with formulas/manifests.

Decision Criteria

Consider implementing this when:

• Project has 100+ stars (indicates broader adoption)
• Multiple users request package manager support
• You have other tools to add to these repos (amortize maintenance cost)
