## Context
This PR updates a misleading comment in the remote edit merge path in
the text CRDT.
At `crates/text/src/text.rs`, the code skips fragments when
`fragment.timestamp > timestamp`, but the comment described this as
"lower lamport timestamp." In this codebase, Lamport ordering is
ascending (`value`, then `replica_id`), so `>` means a higher Lamport
timestamp.
This change is comment-only and does not change runtime behavior.
## How to Review
1. Open `crates/text/src/text.rs` and inspect the updated two-line
comment above the `while let Some(fragment) = old_fragments.item()` loop
in `apply_remote_edit`.
2. Confirm the condition directly below is unchanged:
`fragment.timestamp > timestamp`.
3. (Optional) Cross-check Lamport ordering in
`crates/clock/src/clock.rs` (`impl Ord for Lamport`) to confirm the
wording.
