quest: clean up second release-backport batch after landing

[kixelated]

Problem

Six main-side quests tracked the second batch of release backports. They are done, so the quests, their parent questline, and its quest/m1/README.md entry should go.

Approach

All six backports merged into release: #5213 (JS requester FIN), #5222 (repeated unknown SETUP options), #5224 (legacy request parameters), #5225 (namespace fills), #5228 (quiet catalog floor), and #5230 (FETCH requester FIN).

This deletes quest/m1/release-backports/ (README plus six children) and its m1 index entry. Merged main to resolve a one-line conflict in quest/m1/README.md (main had already removed the completed ietf-dispatch-headers entry). No other references to the deleted paths remain.

Impact

• Quest bookkeeping only; no public API, ABI, or wire change.

Validation

• quest check passes on the merged head.
• grep -r release-backports finds no remaining references.

Automated review by review (OpenAI)

Reviewed c46b2a6. No actionable findings.

The cleanup is appropriate: #5213, #5222, #5224, #5225, #5228 and #5230 are all merged into release. The current diff removes only the completed quest family and its index entry, with no API or wire impact.

Verification: GitHub-only review of the full diff, current index and prerequisite merge states. I did not run quest check or an exhaustive head-tree reference scan; Check and Test are still in progress.

Merge summary: all six second-batch backports (#5213, #5222, #5224, #5225, #5228, #5230) merged into release, so the release-backports questline is deleted. Merged main to resolve the quest/m1/README.md conflict (both sides removed a different line). No remaining references to the deleted paths. quest check passes. Codex and OpenAI reviewed head c46b2a6 and found nothing. Check and Test pass. No outstanding decisions.
