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Bootstrap repo (mosaic/bootstrap) is now fully superseded: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- skills-local/ superseded by monorepo skills/ with mosaic-* naming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/

+# Mosaic Profiles
+
+Profiles are runtime-neutral context packs that can be consumed by any agent runtime.
+
+## Layout
+
+- `domains/`: regulated-domain and security context (HIPAA, fintech, crypto, etc.)
+- `tech-stacks/`: stack-specific conventions and quality checks
+- `workflows/`: reusable execution workflows
+
+## Runtime Split
+
+- Runtime-neutral content belongs here under `~/.config/mosaic/profiles`.
+- Runtime-specific settings belong under `~/.config/mosaic/runtime/<runtime>/...`.
+
+Current runtime overlay example:
+
+- `~/.config/mosaic/runtime/claude/settings-overlays/jarvis-loop.json`
+
+## Claude Compatibility
+
+`mosaic-link-runtime-assets` prunes legacy preset symlink trees from `~/.claude` so Mosaic remains canonical and Claude uses runtime overlays that reference Mosaic paths directly.
