* add iterator slice helpers and channel dedup/tee
* note unbounded memory growth in Distinct; simplify Take
* avoid extra iteration in Take/TakeWhile/TakeFilter and precompute Sliding step
* avoid reallocations in Sliding overlap shift
* sliding uses ring buffer
* refactor Sliding and expand TestSliding
* Remove Tee; add TakeFilter variant, rewrite Sliding
* remove channel Distinct/DistinctBy
* TakeFilter/TakeFilterI for slice
* Revert "TakeFilter/TakeFilterI for slice"
This reverts commit 6d2fcdc07b.
* doc add new helpers to llms.txt

Filters elements and takes the first n matches. Stops once n matches are found.
TakeFilter
seq := func(yield func(int) bool) {
yield(1)
yield(2)
yield(3)
yield(4)
yield(5)
yield(6)
}
result := it.TakeFilter(seq, 2, func(x int) bool {
return x%2 == 0
})
var out []int
for v := range result {
out = append(out, v)
}
// out contains [2, 4]
TakeFilterI
result := it.TakeFilterI(seq, 2, func(x, index int) bool {
return x%2 == 0 && index < 4
})
// out contains [2, 4]
