Patch Changes

• Rename the ok install-skill CLI command to a deliberately hidden, unadvertised ok cowork. The old name implied an automatic install it never performed — it builds the openknowledge.skill bundle and opens the Claude Desktop App for a manual upload (the only path to the separate Skills list Claude Chat & Cowork read, which ok init's editor wiring can't reach). The command is now registered hidden (absent from ok --help), and ok init no longer pushes a hint toward it — it is a power-user escape hatch discovered pull-only via the Open Knowledge skill. The underlying bundle build and the POST /api/install-skill route are unchanged.
