Add Homebrew Installation Support for Kelos

[stearz]

As a Kelos user on macOS or Linux
I want to install Kelos via Homebrew
So that I can easily install and manage Kelos using my package manager, consistent with my workflow for other tools

Description

Homebrew is a widely used package manager on macOS and Linux. Adding Homebrew support will improve the installation experience and discoverability for users who prefer package managers over manual installation.

Acceptance Criteria

• Kelos CLI binary is available via brew tap kelos-dev/kelos
• Users can install with brew install kelos
• Users can update with brew upgrade kelos
• Installation works on:
  • macOS (Intel - x86_64)
  • macOS (Apple Silicon - ARM64)
  • Linux (x86_64)
  • Linux (ARM64)
• Homebrew formula is automatically updated on every release
• Release bundles contain checksums for verification
• Documentation mentions Homebrew as the recommended installation method

Kelos Triage Report

Kind: kind/feature
Priority: priority/important-longterm — Valuable quality-of-life improvement for adoption, but not blocking any current functionality
Actor: needs human — Requires creating an external Homebrew tap repository (homebrew-kelos) on GitHub, configuring repository secrets/permissions, and making product decisions about release automation strategy (e.g., goreleaser vs custom formula updates)

Status: STILL VALID

Evidence:

• No merged PRs or commits reference Homebrew or brew support
• No .goreleaser.yml or Homebrew formula files exist in the codebase
• The current release workflow (.github/workflows/release.yaml) already builds multi-platform CLI binaries and uploads checksums to GitHub releases — this is a good foundation to build on
• No Homebrew tap repository exists yet, which would need to be created under the kelos-dev org

Duplicates found: None found

Recommendation: KEEP OPEN — This requires human decisions about: (1) creating a homebrew-kelos tap repository, (2) choosing an automation approach (goreleaser brews config vs standalone formula update workflow), and (3) organizational access to set up the tap repo. Once those decisions are made, the implementation itself could be delegated.

The PR #818 as it is now will not work. - Unfortunately my Claude was very sure that we can reuse the kelos repo for the tap as well.

If you are ok with the feature just create a homebrew-tap or homebrew-kelos repo and tell me which name it should be, I will then update the PR accordingly.

For reference: https://docs.brew.sh/How-to-Create-and-Maintain-a-Tap

looks ok but I am unfamiliar with managing the homebrew package.

anyway I made https://github.com/kelos-dev/homebrew-tap can you open a PR so that I can test it.
