midasmatterhorn ea826b11cc engine: refuse negative indices instead of targeting element 0
`version.*`, `pointColor.delete` and `redeye.catchlight`/`redeye.delete`
parsed `index` with `f64_req(..)? as usize`. Rust's float-to-int cast
saturates, so `index: -1` became 0 and the bounds checks never saw a
negative: a caller sending `index: -1` silently deleted, restored or
renamed version 0 (or the first point-colour sample / red-eye correction)
and got `ok` back. `history.restore` already guards this and `spot_index`
uses `as_u64`.

New `index_req` helper in `cmd/mod.rs` (the same finite, non-negative
guard) is used by the five sites. Behaviour for valid indices is
unchanged.

Regression test `negative_indices_are_refused` creates a version, then
asserts `version.delete/restore/rename` with `index: -1` error and version
0 is untouched (before the fix the first one deletes it).
