Schedule: Add unit tests to interactive/packages/utils/src/mimic-filter.ts

[gitauto-ai]

Resolves #7

Summary

Add comprehensive unit tests for interactive/packages/utils/src/mimic-filter.ts to raise line/statement/function/branch coverage from 0% and validate behavior across happy paths and edge cases.

Test Patterns

• Filters elements correctly based on a predicate (happy path)
• Predicate receives (value, index, collection) with correct values
• Returns empty array when no elements match
• Preserves input immutability (does not modify original collection)
• Maintains result order of matching elements
• Handles empty input collection
• Handles null/undefined input according to expected behavior (graceful return or explicit error)
• Throws or errors when predicate is not a function
• Supports optional thisArg/options when provided (if applicable)
• Handles sparse arrays and mixed-type elements
• Covers branching paths such as early exits/default behaviors (if present)
