v0.6.0

Fixed

• Plan preview renders before approval. The auto-render hook is now PreToolUse on ExitPlanMode, not PostToolUse. PostToolUse resolves only after you approve a plan, so the preview appeared only post-approval and, via --latest, could render the previous plan mid-iteration. The preview now pops up as the plan is presented and refreshes on every revision.

Added

• preview-plan.mjs --hook. A first-class hook mode: it reads the ExitPlanMode tool-call JSON on stdin and renders that exact plan (tool_input.plan), so no shell wrapper is needed to wire the PreToolUse hook. It falls back to the newest saved plan when the payload carries none, and always exits 0 so it can never block ExitPlanMode. The repo's own .claude/settings.json and the README now use PreToolUse + --hook.

Changed

• Plan preview works as an installed plugin. /mdp-preview-plan now invokes the converter via ${CLAUDE_PLUGIN_ROOT} (with a repo-root fallback) instead of a CWD-relative path, so it works for /mdp plugin users in any project, not just inside this repo.
