feat: integrate framework files into monorepo under packages/mosaic/framework/

Moves all Mosaic framework runtime files from the separate bootstrap repo
into the monorepo as canonical source. The @mosaic/mosaic npm package now
ships the complete framework — bin scripts, runtime configs, tools, and
templates — enabling standalone installation via npm install.

Structure:
  packages/mosaic/framework/
  ├── bin/          28 CLI scripts (mosaic, mosaic-doctor, mosaic-sync-skills, etc.)
  ├── runtime/      Runtime adapters (claude, codex, opencode, pi, mcp)
  ├── tools/        Shell tooling (git, prdy, orchestrator, quality, etc.)
  ├── templates/    Agent and repo templates
  ├── defaults/     Default identity files (AGENTS.md, STANDARDS.md, SOUL.md, etc.)
  ├── install.sh    Legacy bash installer
  └── remote-install.sh  One-liner remote installer

Key files with Pi support and recent fixes:
- bin/mosaic: launch_pi() with skills-local loop
- bin/mosaic-doctor: --fix auto-wiring for all 4 harnesses
- bin/mosaic-sync-skills: Pi as 4th link target, symlink-aware find
- bin/mosaic-link-runtime-assets: Pi settings.json patching
- bin/mosaic-migrate-local-skills: Pi skill roots, symlink find
- runtime/pi/RUNTIME.md + mosaic-extension.ts

Package ships 251 framework files in the npm tarball (278KB compressed).

+# Repo Mosaic Linkage
+
+This repository is attached to the machine-wide Mosaic framework.
+
+## Load Order for Agents
+
+1. `~/.config/mosaic/STANDARDS.md`
+2. `AGENTS.md` (this repository)
+3. `.mosaic/repo-hooks.sh` (repo-specific automation hooks)
+
+## Purpose
+
+- Keep universal standards in `~/.config/mosaic`
+- Keep repo-specific behavior in this repo
+- Avoid copying large runtime configs into each project
+
+## Optional Quality Rails
+
+Use `.mosaic/quality-rails.yml` to track whether quality rails are enabled for this repo.
+
+Apply a template:
+
+```bash
+~/.config/mosaic/bin/mosaic-quality-apply --template <template> --target .
+```
+
+Verify enforcement:
+
+```bash
+~/.config/mosaic/bin/mosaic-quality-verify --target .
+```
+
+## Optional Matrix Orchestrator Rail
+
+Repo-local orchestrator state lives in `.mosaic/orchestrator/`.
+
+Run one cycle:
+
+```bash
+~/.config/mosaic/bin/mosaic-orchestrator-matrix-cycle
+~/.config/mosaic/bin/mosaic-orchestrator-run --once
+```
+
+Run continuously:
+
+```bash
+~/.config/mosaic/bin/mosaic-orchestrator-run --poll-sec 10
+```
+
+Bridge events to Matrix:
+
+```bash
+~/.config/mosaic/bin/mosaic-orchestrator-matrix-publish
+~/.config/mosaic/bin/mosaic-orchestrator-matrix-consume
+```
+
+Run until queue is drained (syncs from `docs/tasks.md` first):
+
+```bash
+~/.config/mosaic/bin/mosaic-orchestrator-drain
+```
+
+Set worker command if auto-detect does not match your CLI:
+
+```bash
+export MOSAIC_WORKER_EXEC="codex -p"
+# or
+export MOSAIC_WORKER_EXEC="opencode -p"
+```
+
+Use repo helper (foreground or detached):
+
+```bash
+bash scripts/agent/orchestrator-daemon.sh drain
+bash scripts/agent/orchestrator-daemon.sh start
+bash scripts/agent/orchestrator-daemon.sh status
+bash scripts/agent/orchestrator-daemon.sh stop
+```
