2026.4.6

Added

• Added a markdown preview annotation workbench, shared annotation helpers, and update/remove flows so inline markdown annotations can be created and iterated from the command center with stronger regression coverage.
• Added AI-assisted quality-plan entries and the corresponding markdown-annotation rollout plan so the new workflow is documented before release.

Changed

• Updated README and localized quick-start version examples to 2026.4.6.
• Refined the frontend visual spec and split-layout shell behavior so narrow workspaces fall back to the compact inspector rail using actual workspace width.

Fixed

• Fixed chat bubble sizing, attachment layout, and async assistant mirroring so tighter layouts stay readable while markdown preview annotation interactions remain anchored correctly.
• Fixed prepared-prompt dispatch aliasing and OpenClaw client request handling regressions uncovered while landing the markdown annotation update flow.
