chore: migrate workspace to moon/proto node stack (#17)

## Summary
- migrate from deno-root layout to a Node + pnpm workspace layout
- move package logic under `packages/cssforge` and add moon v2
project/task configuration
- migrate package scripts into moon tasks and remove `scripts` blocks
from repo package manifests
- keep JSR publishing support via moon tasks and update release
automation
- add example projects and task wiring for e2e/dev flows

## Verification
- ran CI-equivalent workflow locally:
  - `proto install`
  - `proto run pnpm -- install --frozen-lockfile`
  - `moon run :format`
  - `moon run :test`
  - `moon run :typecheck`

Supersedes #16 (opened from the wrong branch).

+description: This skill should be used when the user asks to "configure moon", "set up moonrepo", "create moon tasks", "run moon commands", "configure moon workspace", "add moon project", "moon ci setup", "moon docker", "moon query", "migrate to moon v2", or mentions moon.yml, .moon/workspace.yml, .moon/toolchains.yml, moon run, moon ci, or moonrepo in general.

+# moon - Polyglot Monorepo Build System
+
+moon is a Rust-based repository management, task orchestration, and build system for polyglot monorepos. It provides smart caching, dependency-aware task execution, and unified toolchain management.
+
+> **moon v2 is now available.** Run `moon migrate v2` to migrate. See `references/v2-migration.md` for breaking changes.
+
+## When to Use moon
+
+- Managing monorepos with multiple projects/packages
+- Orchestrating tasks across projects with dependencies
+- Caching build outputs for faster CI/local builds
+- Managing toolchain versions (Node.js, Rust, Python, Go, etc.)
+- Generating project and action graphs
+
+## Quick Reference
+
+### Core Commands
+
+```bash
+moon run <target>          # Run task(s)
+moon run :lint             # Run in all projects
+moon run '#tag:test'       # Run by tag
+moon ci                    # CI-optimized execution
+moon check --all           # Run all build/test tasks
+moon query projects        # List projects
+moon project-graph         # Visualize dependencies
+```
+
+### Target Syntax
+
+| Pattern        | Description                     |
+| -------------- | ------------------------------- |
+| `project:task` | Specific project and task       |
+| `:task`        | All projects with this task     |
+| `#tag:task`    | Projects with tag               |
+| `^:task`       | Upstream dependencies (in deps) |
+| `~:task`       | Current project (in configs)    |
+
+### Configuration Files
+
+| File                   | Purpose                                  |
+| ---------------------- | ---------------------------------------- |

+
+- run: moon ci :build :test
+
+- uses: moonrepo/run-report-action@v1

+
+### Parallelization with Matrix
+
+```yaml
+strategy:

+```
+
+### Affected Detection
+
+```bash
+moon run :test --affected             # Only affected projects
+moon run :lint --affected --status staged  # Only staged files
+moon ci :test --base origin/main      # Compare against base
+moon query changed-files              # v2: renamed from touched-files
+```
+
+## Docker Support
+
+```bash
+moon docker scaffold <project>     # Generate Docker layers
+moon docker setup                  # Install toolchain in Docker
+moon docker prune                  # Prune for production
+moon docker file <project>         # Generate Dockerfile
+```
+
+## Moon Query Language (MQL)
+
+```bash
+# Filter projects
+moon query projects "language=typescript && projectType=library"
+moon run :build --query "tag=react"
+
+# Operators: =, !=, ~, !~, &&, ||
+# Fields: project, language, stack, tag, task, taskType
