feat: complete framework migration — PowerShell, adapters, guides, profiles, tests

Completes the bootstrap repo migration with remaining files:
- PowerShell scripts (.ps1) for Windows support (bin/ + tools/)
- Runtime adapters (claude, codex, generic, pi)
- Guides (17 .md files) and profiles (domains, tech-stacks, workflows)
- Wizard test suite (6 test files from bootstrap tests/)
- Memory placeholder, audit history

Bootstrap repo (mosaic/bootstrap) is now fully superseded:
- All 335 files accounted for
- 5 build config files (package.json, tsconfig, etc.) not needed —
  monorepo has its own at packages/mosaic/
- skills-local/ superseded by monorepo skills/ with mosaic-* naming
- src/ already lives at packages/mosaic/src/
