perf: optimize Substring to work directly with strings instead of converting to runes ( #822 )
...
* perf: optimize Substring to work directly with strings instead of converting to runes
- Rewrite Substring to iterate over string bytes directly, avoiding full []rune conversion
- Improve performance for long strings by only processing necessary portions
- Add comprehensive test cases for Unicode handling, invalid UTF-8, and edge cases
- Add BenchmarkSubstring to measure performance improvements
- Improve documentation with detailed parameter descriptions
- Handle invalid UTF-8 sequences by converting to []rune when needed

* Enhance substring documentation with Unicode details
Returns a substring starting at the given offset with the specified length. Supports negative offsets; out-of-bounds are clamped. Operates on Unicode runes (characters) and is optimized for zero allocations.

fix: make Ellipsis operate on runes instead of bytes to prevent Unicode truncation ( #796 )
...
* fix: make Ellipsis operate on runes instead of bytes to prevent Unicode truncation
The Ellipsis function previously used byte-based length counting (len(str))
and byte-based slicing (str[:length-3]), which could split multi-byte
Unicode characters in the middle, producing garbled output.
This changes the function to use []rune conversion so the length parameter
counts Unicode code points instead of bytes. Emoji, CJK ideographs, and
other multi-byte characters are now never split in the middle.
Fixes #520

* refactor: avoid rune slice allocation in Ellipsis
Use range-based iteration to count runes without allocating a []rune
slice, per reviewer suggestion. The early-return for length < 3 is
kept explicit for clarity.
* Simplify Ellipsis: remove early return for length < 3, reuse ellipsis const
