Sync upstream changes through 2026-06-25 - #69

Summary

• Sync upstream goose changes from e4f8b61b5 through 24166fc34 (17 commits)
• Remove upstream tunnel/gateway/mesh/session-sharing UI and REST surface while preserving ApeMind desktop branding and fork-only UX defaults
• Bring in ACP scheduler custom requests, agent mention/slash-command autocomplete, last-message session metadata, provider thinking-buffer fixes, and generated API/SDK updates

ApeMind conflict handling

• Kept ApeMind Agent productName/description and existing updater/release artifact naming
• Kept ApeMind workflow wording (Workflow/Workflows/工作流) and branded i18n copy
• Kept the parameter cancel flow returning to /pair
• Kept the BaseChat ApeMind watermark and saved-workflow trust behavior
• Updated the ApeCloud-only scheduler test mock after upstream moved scheduler calls to ACP
• Kept PR website preview resilient when Cloudflare secrets are absent
