[WIP] Update package name sanitization behavior

[Copilot]

Update Package Name Sanitization in create-package Tool

Problem

The current implementation uses tr ' _' '-' which only handles spaces and underscores, but doesn't handle other whitespace characters like tabs. This causes tabs to be removed instead of converted to dashes.

Solution

• Understand the current implementation and identify the issue
• Update the sanitization logic in create-package script
  • Changed tr ' _' '-' to tr -s '[:space:]_' '-' to handle all whitespace
  • The -s flag squeezes consecutive characters into one
  • [:space:] matches all whitespace (spaces, tabs, newlines, etc.)
• Update README.md documentation to reflect the improved sanitization
• Test the changes with various inputs including tabs, multiple spaces, and special characters
• Verify all examples from the problem statement work correctly

Changes Made

1. create-package script (line 46): Changed tr ' _' '-' to tr -s '[:space:]_' '-'

   • Now handles all whitespace characters (tabs, multiple spaces, etc.)
   • The -s flag automatically collapses consecutive whitespace into a single dash

2. README.md: Updated sanitization documentation to clarify that all whitespace characters are handled

Examples Validated ✓

• "my repo" -> "my-repo" ✓
• "my ^ repo2" -> "my-repo2" ✓
• "my\trepo" (with tab) -> "my-repo" ✓
• "my\t\trepo" (multiple tabs) -> "my-repo" ✓
• "TEST___REPO" (multiple underscores) -> "test-repo" ✓

Original prompt

Update the existing PR in punppis/linux-utils (PR #1: #1, branch copilot/add-create-package-tool) to adjust package name sanitization behavior.

New sanitization rules (must match examples):

• Lowercase everything.
• Convert any run of whitespace characters (including multiple spaces, tabs) into a single dash -.
• Remove special characters.
• Allowed characters in final name: lowercase letters a-z, digits 0-9, and dash -.
• Collapse multiple dashes to a single dash, and trim leading/trailing dashes.

Examples:

• "my repo" -> "my-repo"
• "my ^ repo2" -> "my-repo2"

Notes:

• The current implementation uses tr ' _' '-' which does not collapse runs of whitespace into a single dash before removing special chars in all cases; update accordingly.
• Update README documentation in the PR if it mentions sanitization specifics.
• Keep Debian/Ubuntu compatibility; prefer POSIX-ish utilities (tr, sed, awk) available by default.
