[Copilot]

Package Manager Implementation - COMPLETED ✅

This PR implements a complete client-side package manager for HypnoScript as part of the CLI, following npm/bun patterns with hypnotic theming.

Key Features Delivered

✨ Hypnotic Theming: Uses ritualName, mantra, anchors, deepAnchors, suggestions, etc.
✨ npm-like Interface: Familiar commands matching npm patterns
✨ Short Alias: Use either hypnoscript or hyp - both work identically
✨ Templates: CLI and library project templates with consistent entry points
✨ Lock Files: Reproducible builds with trance-lock.json
✨ Robust Validation: Semver version requirement validation for all dependency specs
✨ Script Execution: ✅ IMPLEMENTED - Run suggestions (scripts) from manifest with proper shell parsing
✨ Quoted Arguments: Commands with quoted strings are parsed correctly using shlex (e.g., echo "Hello World")
✨ Metadata: Full support for authors, links, keywords, license

Command Structure

# Both forms work identically
hypnoscript <command>
hyp <command>

# Execute HypnoScript files directly
hypnoscript exec program.hyp
hyp exec program.hyp

# Run scripts from trance.json (like npm run) - FULLY FUNCTIONAL!
hypnoscript run test        # Actually executes the 'test' command
hyp run focus               # Actually executes the 'focus' command

# Package management with correct syntax
hypnoscript init --template cli
hyp add pkg --version "^1.0.0"
hypnoscript add pkg --version "^1.0.0" --dev
hypnoscript install
hyp list

Script Execution Feature ✅ IMPLEMENTED

The run command now fully executes commands defined in trance.json suggestions with proper shell argument parsing:

• Command parsing: Uses shlex crate for proper shell-style parsing
• Quoted arguments: Correctly handles quoted strings with spaces
• Process execution: Uses std::process::Command for actual execution
• Interactive support: Inherits stdin/stdout/stderr for interactive commands
• Error handling: Proper handling of missing executables and non-zero exit codes
• Exit code propagation: Command failures are properly reported

Example:

{
  "suggestions": {
    "greet": "echo \"Hello World\"",
    "test": "cargo test --all"
  }
}

$ hypnoscript run greet
📜 Running suggestion 'greet': echo "Hello World"
Hello World

Testing & Quality

• ✅ 6 new tests, all passing
• ✅ 207 total tests passing (6 package manager + 201 existing)
• ✅ No clippy warnings
• ✅ Code formatted with rustfmt
• ✅ Comprehensive error handling
• ✅ Well-documented APIs
• ✅ Both binary aliases tested and working
• ✅ Improved version validation with semver::VersionReq
• ✅ Command execution tested with various scenarios including quoted arguments
• ✅ All documentation examples verified for correctness
• ✅ Clean, well-formatted documentation

Files Added/Modified

• hypnoscript-cli/src/package.rs (new, 654 lines) - improved validation logic
• hypnoscript-cli/src/main.rs (modified, command renaming, constants extracted, proper shell parsing with shlex)
• hypnoscript-cli/Cargo.toml (modified, added [[bin]] sections for aliases, added shlex dependency)
• README.md (updated with package manager section, translated to English, fixed examples, cleaned formatting)
• PACKAGE_MANAGER.md (new, complete usage guide)
• IMPLEMENTATION_SUMMARY_PACKAGE_MANAGER.md (new, detailed summary with corrected examples)
• examples/trance.json (new, example manifest)

All requirements from the issue have been successfully implemented! 🎉

This section details on the original issue you should resolve

<issue_title>Package Manager</issue_title>
<issue_description>HypnoScript needs a reliable package manager. It should split in 2 parts, the client, which should be part of the CLI and the server, which should run on independent infrastructure in containers, should be horizontally scalable and have a webui, including administrative and user views.

As part of this project, the Client side should be developed as Part of the CLI. It should use a new manifest standard, trance.json, following the following scheme:

{
  "ritualName": "hypno-cli-starter",
  "mantra": "0.1.0",
  "intent": "cli",
  "induction": {
    "description": "Starter template for a HypnoScript-powered command-line app focused on status and monitoring commands.",
    "entryScript": "src/main.hyp",
    "keywords": ["hypnoscript", "cli", "template", "starter"],
    "license": "MIT"
  },
  "hypnotists": [
    {
      "name": "Your Name",
      "role": "Lead Hypnotist",
      "contact": "mailto:you@example.com"
    }
  ],
  "auras": {
    "repository": "https://github.com/your-org/hypno-cli",
    "homepage": "https://your-org.dev/hypno-cli",
    "documentation": "docs/index.md",
    "supportChannel": "https://chat.your-org.dev/hypno"
  },
  "suggestions": {
    "focus": "hypnoscript run src/main.hyp -- help",
    "status": "hypnoscript run src/main.hyp -- status",
    "pulse": "hypnoscript run src/main.hyp -- pulse",
    "watch": "pwsh scripts/watch.ps1 help",
    "test": "hypnoscript run tests/smoke.hyp"
  },
  "anchors": {
    "hypnoscript-runtime": "^1.0.0",
    "hypnoscript-cli": "^1.0.0"
  },
  "deepAnchors": {
    "@hypno/testing-lab": "^0.3.0"
  },
  "channels": {
    "binary": "hypno-cli",
    "entry": "focus",
    "targets": ["windows-x64", "linux-x64", "macos-universal"],
    "telemetry": {
      "enabled": false,
      "endpoint": ""
    }
  },
  "triggers": {
    "preFocus": "scripts/pre-focus.hyp",
    "postRelax": "scripts/post-relax.hyp"
  }
}

It should also use trance-lock.json files for handling peer dependencies.

In usage it should orientate on npm/bun.

It should be efficient and fast, able to work and understand with the other tools, like formatting and linting. </issue_description>

@copilot rund-suggestion is to long, it should be just run

[JosunLP]

@copilot also, it should be possible to use the cli with either hypnoscript or hyp as the software reference

@copilot rund-suggestion is to long, it should be just run

Done! Changed run-suggestion to run (matching npm's pattern) and renamed the file execution command to exec.

# Run scripts from manifest (like npm run)
hypnoscript run test
hypnoscript run focus

# Execute files directly
hypnoscript exec program.hyp

Fixed in commit cb6a95e.

[Copilot]

@copilot also, it should be possible to use the cli with either hypnoscript or hyp as the software reference

Done! Both hypnoscript and hyp are now available as command aliases. They work identically:

# Both forms work
hypnoscript init --template cli
hyp init --template cli

# Mix and match as needed
hypnoscript add pkg@^1.0.0
hyp run test

The CLI automatically shows the correct command name in help text based on which one you use. Fixed in commit 5d47114.
