* 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

* feat: add Take, TakeWhile, FilterTake, Window, and Sliding functions
Add five new slice manipulation functions with tests, examples, and documentation.
* improve Take function safety and add benchmarks
* rename FilterTake to TakeFilter and add README docs
* remove Window and Sliding benchmarks
* apply gofmt and fix linter errors
* apply gofmt and fix linter errors
* feat(intersectby): form transform callback in first position and add support for vaarg
* feat(it): adding loit.IntersectBy
* doc: adding lo.IntersectBy + loit.IntersectBy
* doc: adding lo.IntersectBy + loit.IntersectBy
* style: fix linter
* doc: adding example for lo.IntersectBy
* Fix linting
* Use is.ElementsMatch
This will ignore the ordering of the final intersection. Especially
important when checking old versions of go that do not guarantee an order
when iterating through maps.
* lint: fix inconsistent callback function parameter names
