web command renamed to cdp -- web kept as deprecated alias

The browser-control command `wkappbot web` was renamed to `wkappbot cdp` 2026-05-05 (commit 4ddcd5a4) so the help text and skill docs match the actual transport (Chrome DevTools Protocol). `wkappbot web ...` still works but emits a deprecation warning to stderr and routes to the same handler. CommandHelp.cs --help text and AskCommands.Loop.Persona prompt both refer to `cdp` as primary and `web` as deprecated alias.
