quest(m1): drop the retired TS import shared shift

[kixelated]

Problem

quest/m1/ts-import-shared-shift.md still exists on main, but the mechanism it plans is already gone. #4543 removed the Reanchor shift on dev and made a rewind end the import instead, so there is no shift left to share. Its own body said #4513 was obsolete.

Approach

Delete the quest and its three references:

• quest/m1/README.md (the milestone child list)
• quest/m1/hop-aligned-import.md (a Related link)
• quest/m1/remove-live.md (a Related link)

Per the quest guide, a quest that can no longer be completed is abandoned by deleting it and removing every reference.

Impact

• Public API: none.
• Wire: none.
• No code change. quest check passes at 448 documents.

Follow-ups

• None. The underlying A/V drift on a loop wrap is handled by feat(moq-mux)!: importers publish stream timestamps with monotonic group starts; the catalog clock maps them to wall #4543, which treats a rewind as a hard error rather than shifting, consistent with the rule that a broadcast, track, or group name always means the same content.

Merging: dev already deleted this quest in 798ce05 (every importer refuses a timestamp rewind), so it is only removed from main here. Approved in a quest audit session; #4589 absorbs it afterwards.

No actionable findings in the four-file diff. Deleting the retired quest and its three incoming links is the right, minimal direction: #4543 has merged to dev and actually removed both Reanchor and this quest. Keeping a replacement shift plan on main would contradict that decision; the broadcast-epoch follow-up remains linked from the surviving quests.

Verification: read the complete deletion, both neighboring quest plans, repository instructions and the pinned quest guide; checked the three indexed references and #4543's relevant diff/merge state. The head's Check workflow succeeded. I did not run quest check locally because quest/Nix are unavailable here, and I did not rerun TS behavior tests. Documentation-only change; no public API or wire impact.

Review (MERGE)

Reviewed head 5c8c69e65c6112667926b2336c4204f86d736acc (now landed on main as cead1bd306e9).

Docs/quest cleanup only: deletes the retired ts-import-shared-shift plan and its m1 README entry after #4543 removed Reanchor on dev and closed #4513 as obsolete. Correct abandon per the quest guide; head has no remaining path or Related links to the deleted file (the hop-aligned / remove-live cleanups were already on main via #4589).

Blocking

None.

Non-blocking

1. PR body is slightly stale after the main merge. It still claims this PR edits quest/m1/hop-aligned-import.md and quest/m1/remove-live.md. After merging main, the effective diff is only quest/m1/README.md (−1) and deleting quest/m1/ts-import-shared-shift.md. Harmless now that it has merged; worth remembering when stacking quest-audit PRs.

CI Check/Test were green on the reviewed head.

Verdict: MERGE

This is an automated review, not the maintainer's decision
