Give bots skills: runbooks they load when a job matches

A skill is a runbook: a name, a unique slug, a one-line description of when it applies, and the markdown body. A run only ever sees the slug and description (one load_skill tool carries them), and reads the whole body only when it calls the tool, so a long runbook costs nothing until needed. Skills are the third extension kind beside MCP servers and custom tools, on the same botExtensionsSql path, so per-bot, per-workspace and all-bots grants work the same way, and attachDefaultExtensions hands an every-bot skill to new bots. load_skill is a reserved tool name, so a custom tool cannot shadow it, and a built-in wins a clash. Managed on Settings > Skills; ExtensionRow links each kind to its own page and a skill never reports a failure, since nothing connects or runs.
