Add capture::basic_formatted_to_plain_indexed, which is like capture::basic_formatted_to_plain, but also includes the original index of each plain text substring.

Example

use vt100::capture::basic_formatted_to_plain_indexed;
let mut iter = basic_formatted_to_plain_indexed("hello\x1b[31;1mworld");
assert_eq!(iter.next(), Some((0, "hello")));
assert_eq!(iter.next(), Some((12, "world")));
assert_eq!(iter.next(), None);

Greptile Summary

Adds basic_formatted_to_plain_indexed, reuses it for the existing plain-text iterator, and documents that returned offsets are byte indices.

Confidence Score: 5/5

The PR appears safe to merge.

The changes since the previous review correctly clarify that offsets are byte indices, and no actionable regression or outstanding rule violation remains.
