Summary

Prepare the owner-audited changelogs for the v0.4.1 patch release.

Reasoning

The owner confirmed /cl completed against current main. Release preparation requires those audited records committed on synchronized main; repository rules require a pull request rather than a direct push.

Changes

• Record the /cl updates in the AI and coding-agent changelogs.
• Leave the owner's local AGENTS.md change uncommitted and excluded.
• No implementation, dependency, or public contract changes.

Testing

Validated commit 481880c91f8f305269a57ff417e1236d579b9c2b on Darwin arm64 with Node 22.19.0. These are pre-version-bump artifacts reporting 0.4.0, not a published 0.4.1 release.

• git diff --check passed.
• npm ci --ignore-scripts passed.
• npm run release:local -- --out /tmp/diffex-local-release-v0.4.1 passed, including model generation, full npm run check, offline build, ./test.sh, reviewed packaging, and isolated npm/pnpm/Bun artifact and lifecycle acceptance.
• Outside the repository, both npm- and Bun-installed CLIs passed help, version, and model listing.
• Both installed CLIs returned ok for a real print-mode prompt and a tmux interactive prompt using the configured default ChatGPT model openai-codex/gpt-6.1-sol; interactive /exit completed.
• The existing tmux server warned that extended keys are disabled; ordinary prompt/reply and exit succeeded. No user terminal settings changed.
• No provider credentials or configuration files copied into release artifacts. No version bump, release tag, or publication performed.
