Summary

Audit all commits since v0.4.1 and prepare the missing changelog entries for v0.4.2.

Reasoning

The unreleased sections were empty despite the merged goal-mode and context-management changes.
This owner-requested /cl audit documents those changes before release, duplicates the AI toolkit additions into the CLI changelog, and preserves every historical release section.
The owner confirmed the three release highlights before they were written.

Changes

• Document session-local goal mode, durable archives, private recall, context budgets, evolution suspension, and request failure handling.
• Document historical summary outlines, complete-exchange compaction, protected-context recovery, reduced usage-note cadence, and explicitly requested subagent delegation.
• Document shared AI context-budget exports and the development-launcher and release-acceptance fixes.
• Include the image catalog regenerated by the standard local-release flow: new upstream image models and router metadata, plus removal of an upstream-retired model.
• Leave unchanged packages and historical release records intact.

Testing

• npm run check and npm run build:offline passed during local release preparation.
• The complete isolated non-E2E test suite passed through ./scripts/test.sh.
• git diff --check passed.
• Verified all nine changelogs preserve historical release sections and have unique unreleased subsection headings.
• The same packed candidate passed isolated npm, pnpm, and Bun imports, terminal fixtures, and installation/update/uninstall acceptance.
• Real ChatGPT gpt-6-luna returned ok in print and interactive modes from both npm- and Bun-installed CLIs outside the repository.
• The local-release command completed acceptance but hit macOS /tmp canonicalization when creating its final convenience installs; those installs were resumed successfully under the system temporary directory using the same checked tarball.
• No release tag has been pushed.
