Detailed Description

Exhaustive tests for Pointer_Table class.

These tests cover all operations including edge cases and critical scenarios:

• Basic operations (insert, remove, verify)
• Index recycling behavior
• Heap contraction with free_table cleanup (critical bug fix)
• Exception handling
• Stress tests with random operations
• Memory management and threshold behavior
