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).

+## Continuation Mission
+
+Continue **$mission_name** from existing state.
+
+## Setup
+
+- **Project:** $project_path
+- **State:** docs/TASKS.md (already populated — ${tasks_done}/${tasks_total} tasks complete)
+- **Manifest:** docs/MISSION-MANIFEST.md
+- **Scratchpad:** docs/scratchpads/${mission_id}.md
+- **Protocol:** ~/.config/mosaic/guides/ORCHESTRATOR.md
+- **Quality gates:** $quality_gates
+- **Target runtime:** $target_runtime
+
+## Resume Point
+
+- **Current milestone:** ${current_ms_name:-—} (${current_ms_id:-—})
+- **Next task:** ${next_task:-—}
+- **Progress:** ${tasks_done}/${tasks_total} tasks (${pct}%)
+- **Branch:** ${current_branch:-—}
+
+## Previous Session Context
+
+- **Session:** $prev_session_id ($prev_runtime, $prev_duration)
+- **Ended:** $prev_ended_reason
+- **Last completed task:** $prev_last_task
+
+## Instructions
+
+1. Read \`~/.config/mosaic/guides/ORCHESTRATOR.md\` for full protocol
+2. Read \`docs/MISSION-MANIFEST.md\` for mission scope and status
+3. Read \`docs/scratchpads/${mission_id}.md\` for session history and decisions
+4. Read \`docs/TASKS.md\` for current task state
+5. \`git pull --rebase\` to sync latest changes
+6. Launch runtime with \`$launch_cmd\`
+7. Continue execution from task **${next_task:-next-pending}**
+8. Follow Two-Phase Completion Protocol
+9. You are the SOLE writer of \`docs/TASKS.md\`
