Devin Foleyandgithub-actions[bot] 3c70b3d008 docs(release): curate stable notes for the 2026.921.0-beta.1 promotion (#13785)
## Thinking Path

> - The stable promotion reads `releases/beta/v<beta-version>.md` from
`master` and publishes it as the GitHub Release body.
> - Beta `2026.921.0-beta.1` (source `8f8a0ab7`, 77 commits since
v2026.916.0) just published and starts its 3-day soak, headed for a
stable around 2026-09-24.
> - This PR rewrites the auto-generated draft into release voice during
the soak, per the release checklist.

## Linked Issues or Issue Description

Notes for the stable to be promoted from
[`2026.921.0-beta.1`](https://github.com/paperclipai/paperclip/releases)
— planned as `v2026.924.0`. **If the promotion date slips past
2026-09-24, bump the title and Released date before dispatching
stable.**

## What Changed

- Rewrote `releases/beta/v2026.921.0-beta.1.md` from the 77-entry
scaffold into the standard release-notes structure: overview, Breaking
Changes (legacy Composio broker retirement
[#13758](https://github.com/paperclipai/paperclip/pull/13758); full-auto
execution defaults
[#13686](https://github.com/paperclipai/paperclip/pull/13686)/[#13693](https://github.com/paperclipai/paperclip/pull/13693)),
Highlights, grouped Fixes, Improvements, and an Upgrade Guide
(migrations `0280`–`0283`, `enableMcpAggregators` flag).
- Folded out release-infra noise: CI-only PRs, test-only PRs,
release-notes bookkeeping commits, and the hide/restore Google-connector
pair
([#13551](https://github.com/paperclipai/paperclip/pull/13551)/[#13552](https://github.com/paperclipai/paperclip/pull/13552),
net zero).
- Noted that the composer fix
([#13562](https://github.com/paperclipai/paperclip/pull/13562)) already
shipped early as stable 2026.916.1.

## Verification

- Docs-only; every PR number cited was cross-checked against `git log
dffc2b3ca..8f8a0ab7e`.
- Migration range `0280`–`0283` verified against
`packages/db/src/migrations` diff and attributed per commit.

## Risks

None — documentation only. Content can be edited freely during the soak;
the stable preflight only requires the file to exist on `master`.

## Model Used

Anthropic Claude Fable 5 (`claude-fable-5`) via Claude Code, with tool
use and code execution.
