feat: L0b bootstrap scripts + L1 Go CLI structure

L0b (factory bootstrap):
- bootstrap.ps1 (Windows): pre-checks, interactive config, clone .factory, home.toml
- bootstrap.sh (Linux/Mac): same functionality for bash
- Idempotent re-run with home.toml verification

L1 (Go CLI):
- factory.yaml: manifest schema with components, deps, health-checks
- cmd/factory: Cobra CLI (install/update/status/diagnose)
- pkg/config: home.toml reader
- pkg/manifest: factory.yaml parser + topological sort
- pkg/health: health-check logic (file/dir/mcp_tool/command)

Scripts:
- build.sh: cross-compile for linux/win/darwin × amd64/arm64
- build.ps1: PowerShell cross-compile
