feat: unify install.sh — single installer for framework + npm CLI
- tools/install.sh now installs both components:
1. Framework (bash launcher, guides, runtime configs) → ~/.config/mosaic/
2. @mosaic/cli (TUI, gateway client, wizard) → ~/.npm-global/
- Downloads framework from monorepo archive (no bootstrap repo dependency)
- Supports --framework, --cli, --check, --ref flags
- Delete remote-install.sh and remote-install.ps1 (redundant redirectors)
- Update all stale mosaic/bootstrap references → mosaic/mosaic-stack
- Update README.md with monorepo install instructions
Deprecates: mosaic/bootstrap repo
