Feature: Fuzzy / tolerant name search for monkey lookup

[wiertmir]

Goal

Improve lookup by supporting substring and fuzzy matches (case-insensitive) so users can find monkeys with inexact names.

Why

Better UX for interactive search; tolerates typos.

Light implementation notes

• Add SearchHelper with FindBestMatch(string query, IEnumerable<Monkey> monkeys).
• Implement a simple score: exact match > starts-with > contains > small edit-distance (Levenshtein) threshold. For tiny data sets compute edit distance in O(n*m) fine here.
• Return the best match or null when below threshold; present alternatives when multiple near-matches exist.
• Add unit tests for matching logic with sample inputs.

Files to modify/create

• MyMonkeyApp/Helpers/SearchHelper.cs
• MyMonkeyApp/Program.cs (use helper for details <name> command)
