v1.2.1

Highlights

• Added the AI side-load cache flow with tools/scripts/generate-context-cache.sh, workspace and repo summary outputs under cache/context/, and Workspace Hub detail-surface support for side-load freshness plus generated artifact open actions.
• Added focused Workspace Hub coverage for the side-load generator, repo-details hydration, and stale-versus-fresh side-load behavior.
• Hardened tools/bin/workspace-memory write-heavy commands with a workspace-owned lock so overlapping save-repo, save-workspace, mine-*, and wake-up runs serialize instead of contending on the same local MemPalace store.
• Updated the workflow so an explicit handover-update request now implies the matching MemPalace closeout, plus git status and public-doc alignment checks before closing the chat.
