Draft release notes from this week's merged PRs

Every Friday, draft release notes covering this week's merged pull requests in [org/repo]. Pull every PR merged since the last run, read the titles, descriptions, and linked issues, and sort them into: new features, improvements, bug fixes, and internal or maintenance work — the last group excluded from the public notes but listed for me. Rewrite each entry for users, not engineers: what changed and why they'd care, with no internal jargon or ticket numbers in the public text. Group related PRs into one entry when they ship a single feature, and credit notable community contributions if any. Where a PR's purpose is unclear, check the linked issue before guessing; if still unclear, put it in a needs-clarification list instead of writing something wrong. Deliver the polished public notes in our usual format [paste an example or link], plus the internal list and the unclear items. Don't publish anywhere — these are drafts for my review.
