```
helix: Fix paste crash (#58373)

Closes [#58343](<https://github.com/zed-industries/zed/issues/58343>)

This crash happened because Helix paste restored selection using the raw
clipboard text length, but buffer edits normalize CRLF line endings to
LF before inserting. When pasting CRLF text at or near EOF, the restored
selection could extend past the normalized snapshot length and panic in
`MutableSelectionsCollection::select_ranges`. The fix normalizes the
text before measuring it for selection restoration and adds regression
coverage for CRLF paste in Helix mode.

Release Notes:
