Addresses #93

Context

Adds comprehensive unit test coverage for non-comparison and esoteric/joke sorting algorithms:

• LSDRadix.js: Least Significant Digit (LSD) Radix Sort with 10 buckets for positive numbers, 19 buckets (-9 to +9) for negative numbers, digit extraction passes, and negative sorting toggle (toggleNegativeNumbers).
• RadixSort.js: Classical 3-digit Radix Sort with fixed 30-element visual layout, 10 counting-sort buckets, prefix sum calculation, and swap array copying passes.
• BogoSort.js: Random permutation shuffling sort with sorted verification pass, duplicate element distinguishing letters, and safety abort warning for arrays >= 10 elements.
• DropSort.js: Humorously destructive sort that iterates through array comparing adjacent elements and drops (deletes) any element smaller than its predecessor, shifting subsequent elements left.
• FredSort.js: Partitioned sorting dividing array into ceil(sqrt(n)) sub-arrays, performing insertion sort on each partition, and merging.
• MiracleSort.js: Satirical miracle sort visualizer that displays the array in light blue and waits indefinitely for cosmic rays to sort the data.
• SleepSort.js: Concurrency-inspired sleep sort creating timer labels above each number, counting down to zero, and placing elements into a secondary destination array in ascending order of wakeup.

Changes Made

• Introduced src/algo/__tests__/LSDRadix.test.js:
  • Control registration, sort button, examples dropdown, clear button, and negative numbers toggle checkbox.
  • Validation for empty list, max 18 items, non-numeric values, > 6 digits, and negative numbers when disabled.
  • Positive integer bucket distribution and collection passes.
  • Negative numbers bucket toggle (19 buckets) and negative sorting execution.
  • URL parameter parsing (negative, data).
• Introduced src/algo/__tests__/RadixSort.test.js:
  • Fixed 30-element array structure and 10-element counter array setup.
  • Multi-pass counting sort callback execution (radixSortCallback).
  • List randomization, responsive layout size adjustments (sizeChanged), and UI enable/disable.
• Introduced src/algo/__tests__/BogoSort.test.js:
  • Already-sorted 1-pass verification, unsorted shuffling, and iteration counter.
  • Safety abort warning for list size >= 10.
  • Input validation, duplicates handling, example loading, and UI enable/disable.
• Introduced src/algo/__tests__/DropSort.test.js:
  • Validation for empty list, size > 18, and non-numeric / > 999 values.
  • Sorted non-dropping passes and descending element dropping with array shift animations.
  • URL parameter parsing (data), presets, and UI controls.
• Introduced src/algo/__tests__/FredSort.test.js:
  • Partitioning into sqrt(n) chunks, sub-array drawing, insertion sort passes, and merging.
  • Input validation (max 15 items), duplicates handling, presets, and URL parameter parsing.
• Introduced src/algo/__tests__/MiracleSort.test.js:
  • Input validation, array display, miracle waiting status message, and cell highlighting.
  • Presets, random generator, URL parameter parsing, and UI enable/disable.
• Introduced src/algo/__tests__/SleepSort.test.js:
  • Dual-array representation (source array and secondary destination array).
  • Sleep timer label creation, countdown simulation, and wakeup placement with green sorted cells.
  • Input validation (max 15 items), duplicate handling, presets, and URL parameter parsing.

Test Plan

• Ran npm test -- --watchAll=false (all 7 new test suites pass, 66 unit tests passing; 75 suites, 831 tests passing repository-wide).
• Ran npm run lint and npm run prettier (0 errors, 0 warnings).
