Bootstrap CLI package entrypoint contract and minimal package scripts

[Copilot]

This PR aligns the CLI package bootstrap with the PRD’s MVP contract: an explicit ESM bin entrypoint, a callable CLI runtime entry, and a minimal dev/test script surface. It also establishes a lightweight src/lib module boundary for upcoming command/lib growth.

• CLI bootstrap contract

  • packages/cli/bin/sh1pt.js now behaves as a real entrypoint stub:
    • dynamically imports CLI runtime
    • invokes run(argv)
    • centralizes startup failure handling

• Runtime entry extraction

  • packages/cli/src/index.ts now exports run(argv) so bin execution and module execution share one path.
  • direct execution detection remains supported, but argument parsing now uses commander’s user-argv mode for cleaner invocation semantics.

• Initial command/lib structure

  • added packages/cli/src/lib/logger.ts and wired CLI error output through it, giving src/commands + src/lib a clear baseline split.

• Minimal package scripts

  • packages/cli/package.json now includes a package-level test script while keeping existing dev behavior intact.

// packages/cli/bin/sh1pt.js
#!/usr/bin/env node
import('../dist/index.js')
  .then(({ run }) => run(process.argv.slice(2)))
  .catch((err) => {
    console.error(err?.message || err);
    process.exit(1);
  });

Issue: Bootstrap CLI package structure for sh1pt

Requirements:

• Set up the initial CLI package structure for sh1pt as described in the PRD.
• Create the packages/cli directory.
• Initialize package.json with the correct ESM and bin setup.
• Create bin/sh1pt.js with CLI entrypoint stub.
• Create a basic src/ structure for commands and lib modules.
• Add minimal scripts (dev, test).
• No TypeScript or extra dependencies for MVP.

Repository: profullstack/sh1pt
Parent tracking issue: #422
Target issue: #425

Please implement the changes, create a branch, commit them, and open a PR with a clear summary referencing #425.

The following is the prior conversation context from the user's chat exploration (may be truncated):

User: Create me a sub-issue for @profullstack/sh1pt/issues/422 to

Assistant: What should the sub-issue cover?

If you want, I can draft it for you. A good next sub-issue for profullstack/sh1pt#422 would be something like:

• Bootstrap CLI package structure
• Implement local registry loader
• Add actions list and actions info commands
• Build install planner and diff preview
• Implement actions audit workflow scanner
• Add sample action package: vu1nz-scan
• Add skill package support and modern-web sample

If you want, reply with either:

1. Just a title, and I’ll create the sub-issue, or
2. Title + description, and I’ll create it, or
3. “Draft the best first sub-issue”, and I’ll draft and create it under profullstack/sh1pt#422.

User: create a sub-issue for each outstanding thing left in the original ticket the prd.

Assistant: Drafted the sub-issues for profullstack/sh1pt#422 for your review.

    Implement a local registry loader for sh1pt CLI. The CLI should be able to load the action, skill, and pack registry files from the local `packages/registry/` directory, as described in the PRD. This loader will be used by CLI commands to discover actions, skills, and packs.

    Implement the `actions list` and `actions info <name>` commands for sh1pt CLI as per the PRD. These commands should:
    - Query the local registry loader
    - List available action packages
    - Show detailed info for a selected action
    - Output required metadata (trust level, publisher, paths, manifest description, etc.)

    Implement an install planner and diff preview feature for sh1pt CLI. This should:
