feat(ts): translate the rest of str's searches and text iterators

 - [A vector's exact capacity as it shrinks](/quest/m3/ts-vec-exact-capacity.md) - a deque made from a `Vec` splits its slices where std's does
 - [A B-tree's searches call Ord as std's do](/quest/m3/ts-btree-search-order.md) - a B-tree's lookups and inserts call a key's own `Ord` in std's order and number

-- [The rest of str's searches](/quest/m3/ts-str-searches.md) - `find`, `strip_prefix`, `replace`, `rsplit`, `splitn`, `matches`, `lines`, and the rest of `str`'s searches translate
 - [Adding to a String](/quest/m3/ts-string-add.md) - `String + &str` translates as `+=` does
 - [The rest of a vector's methods](/quest/m3/ts-vec-rest.md) - `append`, `resize`, `split_off`, `try_reserve`, and `Vec::from(VecDeque)` translate
