Add CSV Row Viewer standalone tool

[rodrigogiraoserrao]

Motivation

• Provide a small standalone web tool to upload a CSV and inspect individual data rows one-at-a-time for easier browsing and debugging.

Description

• Add csv-row-viewer.html, a standalone HTML/JS tool that accepts a CSV file, treats the first row as the header, and renders each subsequent row as a key/value table with per-row pages.
• Implement a client-side CSV parser supporting quoted fields and escaped quotes and simple CR/LF handling in csv-row-viewer.html (function parseCsv).
• Add row navigation controls including Previous row, Next row, and a numeric Jump to row input with validation and disabled-state handling for navigation buttons.
• Add csv-row-viewer.docs.md with a short description so the tool is picked up by the repository metadata/indexing.

Testing

• Ran python gather_links.py which processed files and updated tools.json successfully (output: "Processed 29 files" and "Generated metadata for 28 tools in tools.json").
