Complete missing proxy modules in src/algorithms

[Copilot]

The src/algorithms/ proxy layer was incomplete—missing sorting algorithms and the entire searching directory, despite implementations existing in interview_workbook/.

Changes

src/algorithms/sorting/

• Added heap_sort, merge_sort, quick_sort to __all__ and created corresponding proxy modules

src/algorithms/searching/ (new)

• Created directory with __init__.py using lazy loading pattern
• Added proxy modules: advanced_search, binary_search, linear_search, quickselect

Usage

# Previously incomplete/missing, now available:
from algorithms.sorting import heap_sort, merge_sort, quick_sort
from algorithms.searching import binary_search, linear_search, quickselect

arr = [64, 34, 25, 12, 22, 11, 90]
sorted_arr = merge_sort.merge_sort(arr)
index = binary_search.binary_search(sorted_arr, 25)

All proxy modules follow the established pattern with wildcard imports from interview_workbook.

Original prompt

Can you go through each demo/algorithm and add the missing parts until all are complete

Pull Request Overview

This PR adds proxy modules for three sorting algorithms (heap_sort, merge_sort, quick_sort) and four searching algorithms (advanced_search, binary_search, linear_search, quickselect) to enable imports from src.algorithms.sorting.* and src.algorithms.searching.*. It also creates a new __init__.py for the searching namespace with lazy loading and updates the sorting __init__.py to include the new algorithms in __all__ and documentation.

• Adds proxy modules for heap_sort, merge_sort, and quick_sort in src/algorithms/sorting/
• Adds proxy modules for advanced_search, binary_search, linear_search, and quickselect in src/algorithms/searching/
• Creates lazy loading infrastructure for src/algorithms/searching/init.py
