feat: Add @mosaic/cli-tools package for git operations

New package providing CLI tools that work with both Gitea and GitHub:

Commands:
- mosaic-issue-{create,list,view,assign,edit,close,reopen,comment}
- mosaic-pr-{create,list,view,merge,review,close}
- mosaic-milestone-{create,list,close}

Features:
- Auto-detects platform (Gitea vs GitHub) from git remote
- Unified interface regardless of platform
- Available via `pnpm exec mosaic-*` in monorepo context

Updated docs/claude/orchestrator.md:
- Added CLI Tools section with usage examples
- Updated issue creation to use package commands

This makes Mosaic Stack fully self-contained for orchestration tooling.
