Patch Changes

• Make the open-knowledge-ui entry in .claude/launch.json launchable on Windows. Previously ok init always wrote a /bin/sh chain, so Claude Code Desktop's preview pane could not start the OpenKnowledge UI on Windows (there is no /bin/sh). On Windows, ok init now scaffolds a powershell -NoProfile -NonInteractive -Command <chain> entry that resolves the npm-global ok.cmd shim first, then npx.cmd, then common version-manager/installer paths, and runs ok start --ui-port so the opened folder gets its own collab server. The ok start launch.json repair sweep now recognizes both platforms' canonical shapes on every OS, so a launch.json committed on one platform is never rewritten back and forth by the other, and custom entries are still preserved.
