dedent 1.7.2: verify multiline string indentation removal and options

# Dedent multiline string indentation removal and options in Node.js

`pkg:npm/dedent@1.7.2` provides template tag and function call utilities to strip common leading indentation and leading/trailing blank lines from multiline strings.

## Key Features & Invocations
1. **Tagged Template Literal**: Calling `dedent` as a template tag strips common indentation from multiline text while preserving relative indentation.
2. **Function Call**: Calling `dedent(...)` directly with a string input strips leading indentation identically.
3. **Custom Options (`dedent.withOptions`)**:
   - `alignValues`: When `true`, multiline string interpolations (`${...}`) maintain indentation relative to the interpolation column.
   - `trimWhitespace`: When `false`, leading and trailing whitespace and blank lines are preserved.
   - `escapeSpecialCharacters`: When `false`, backslashes before special characters such as `$` in raw template strings are retained.

Clean-room public code sample — generation instructions

Write a brand-new, minimal, self-contained code sample in this clean-room directory.
Do not copy, paraphrase, or reference any existing project source. Work only from this spec.

A csx.json manifest scaffold already exists. Do not recreate it from memory. Preserve its case.goal, packages and symbols; fill its empty case.contract with exact assertions and correct its environment, commands and verifierAdapter for the files you generate.

Goal: verify pkg:npm/dedent@1.7.2 multiline string indentation removal and options
Kind: HOW

Use EXACTLY these public packages and versions:
  - pkg:npm/dedent@1.7.2
Demonstrate these symbols/APIs:
  - dedent

Rules:
  - One focused purpose; the smallest project that proves the goal.
  - Include a contract test (test/contract.*) that runs OFFLINE and exits 0 exactly when the goal behavior works.
  - Pin every dependency with a lockfile so resolution is reproducible.
  - No secrets, credentials, or tokens. No real URLs (only example.com or localhost). No absolute paths.
  - No personal names, emails, company names, or project identifiers of any kind.
  - No binaries and no generated output (node_modules, dist, target, venv, .git, .env).
  - Keep it under 200 files and 256KB packed.
