Add pkg/ustrings implementing various UTF-8-aware string utilities (Capitalize, ToCamelCase/ToSnakeCase/ToKebabCase, PadLeft/PadRight, Truncate, EllipsisMiddle, Reverse, RemoveWhitespace, SplitAndTrim, JoinNonEmpty, DefaultIfEmpty) plus internal helpers (splitWords, padding/boundary logic). Also add stringify.go providing Stringify with Options to format primitives, slices, arrays, maps, structs and pointers (custom base/format/precision and nil representations). Include comprehensive tests for operations and stringify behavior.

Description
Motivation
We were missing a shared, well-tested set of string utilities, which led to duplicated logic and inconsistent string handling across the codebase. Common operations like case conversion, padding, truncation, and safe stringification were being reimplemented ad‑hoc or avoided altogether.
What this improves
This PR introduces a dedicated
ustringspackage that centralizes frequently needed string operations and a flexibleStringifyhelper for predictable, readable output across primitive types, collections, and structs. The utilities are UTF‑8–safe, cover common edge cases, and come with comprehensive tests, making them reliable building blocks for future features.Additionally, the Docker build is aligned to compile the actual application entry point (
main.go), ensuring the container reflects how the project is meant to be built and run.Overall, this improves consistency, reduces duplication, and makes string handling safer and easier throughout the project.
