Commit Message

warnings: enable unnecessary_view_op, drop redundant `[:]` views

Adds `+unnecessary_view_op` to the workspace warn-list and drops the
unnecessary `[:]` view conversion at every site the lint flags
(~111 sites in `builtin/string_methods.mbt`, `builtin/arrayview*`,
`builtin/readonlyarray*`, `builtin/array*`, `debug/printer.mbt`, etc.).

In two ReadOnlyArray methods (`filter`, `filter_map`), only the outer
`[:]` was removable; the inner `self[:]` is kept because removing it
recurses into the same method (`ReadOnlyArray::filter`/`filter_map`)
instead of dispatching to `ArrayView::filter`/`filter_map`. The lint
flagged both but only one is genuinely unnecessary.
