fix: remove lodash dependency and replace with native utilities

[MarshallOfSound]

This PR removes the lodash dependency from the codebase and replaces all lodash utility functions with native JavaScript equivalents or custom implementations.

Summary

Lodash has been completely removed as a dependency. All lodash function calls have been replaced with:

• Native JavaScript methods (e.g., _.repeat() → String.prototype.repeat(), _.trimEnd() → String.prototype.trimEnd())
• Custom utility functions defined in utils.ts (e.g., upperFirst, lowerFirst, camelCase)
• Native Node.js utilities (e.g., isDeepStrictEqual from node:util)
• Modern JavaScript features (e.g., spread operators, structuredClone(), Object.entries())

Key Changes

• Removed lodash imports from all source files
• Added custom string utilities to utils.ts:
  • upperFirst(): Capitalizes first character
  • lowerFirst(): Lowercases first character
  • camelCase(): Converts strings to camelCase format
• Replaced lodash functions:
  • _.upperFirst() → upperFirst()
  • _.lowerFirst() → lowerFirst()
  • _.camelCase() → camelCase()
  • _.repeat() → String.prototype.repeat()
  • _.trimEnd() → String.prototype.trimEnd()
  • _.concat() → spread operator [...]
  • _.cloneDeep() → structuredClone()
  • _.isEqual() → isDeepStrictEqual() from node:util
  • _.forIn() → Object.entries() with for-of loop
  • _.map() → Array.prototype.map()
  • _.assign() → Object.assign()
• Updated dependencies in package.json:
  • Removed lodash and @types/lodash

Implementation Details

• The custom camelCase() implementation handles word boundaries and maintains compatibility with the original lodash behavior
• isDeepStrictEqual() from Node.js util module provides deep equality checking previously done by _.isEqual()
• Array operations now use native spread operators and array methods instead of lodash utilities
• All functionality is preserved while reducing external dependencies
