Why

#17399 made cmdlog Read hold NextSeq back before the first record whose status is "unfinished", so a follower re-receives a command until it is terminal. That pin had no release condition in two cases:

1. A terminal record whose status is "unfinished": Ended with no exit code (and the runs service mapping runstate.StatusUnfinished) writes an ended line with that status. The record is final, yet Read pinned on it forever.
2. A started line orphaned by a runner crash: Open resumed the seq counter but never closed open seqs, so the record stayed unfinished for the rest of the run.

Either way the follower never advanced, re-receiving the same page forever; with more than limit later records, More was true while NextSeq did not move, so a for page.More loop spun hot against the endpoint.

What

• Read pins on rec.EndedAt == nil (no ended line yet) instead of the status; Status stays as written. The intent of 🐛 fix(crux): cmdlog next_seq never skips an unfinished command's ended line #17399 is kept: a command unfinished when first seen is still re-received until its ended line arrives.
• Open appends an ended line (unfinished, no exit code, reason "runner restarted before the command ended", duration from the started line) for every started seq with no ended line.
• Doc comments on Read and api.CommandPage updated; changelog fragment added.
• Tests: ended-but-unfinished record followed by a completed one advances NextSeq; More with an un-ended first record still clamps to since_seq; Open closes an orphaned started line.

Closes #17410
