Changes

Add Homebrew and Docker installation paths for Foundry. This repository doubles as a custom Homebrew tap, with a formula selecting verified v1.3.0 binaries for macOS/Linux on arm64/amd64. A multi-stage Dockerfile produces a non-root image containing the CLI and all five embedded foundations.

After a successful stable release, a separate distribution workflow builds/tests the tagged source, publishes Linux amd64/arm64 images to GHCR, and updates the latest Homebrew formula on the default branch using the release checksums. Manual dispatch backfills existing releases. Publishing uses only the repository GITHUB_TOKEN; historical releases retain their versioned image without moving latest backward.

Document install/upgrade commands, mounted host output and ownership, Windows/interactive Docker usage, SDK boundaries, formula regeneration, and package visibility/permissions.

Validation

• make ci passed, including invalid/missing/duplicate release checksum coverage and all five template smoke workflows.
• Ruby formula syntax, shell syntax, workflow YAML parsing, and diff checks passed.
• Added CI jobs for Homebrew install/test and offline Docker generation of all five templates.
• Docker daemon is unavailable locally; container checks run in CI.
