WordPress silently drops meta keys that have not been registered with show_in_rest. SEO plugins (Yoast, Rank Math, AIOSEO) do not register theirs by default, so writes via the meta parameter return success while the values never persist. Document the limitation, the list of known-affected keys, what the server warns about today, and the forthcoming mcp-wp-seo-bridge plugin that will register the keys.

Summary
Adds a "Meta field limitations" section to the README explaining that WordPress silently drops meta keys not registered with
show_in_rest. This is the known root cause for SEO plugin meta (Yoast, Rank Math, AIOSEO) appearing to write successfully but never persisting.Doc-only change. No code touched.
Pairs with InstaWP/mcp-wp#17, which adds a runtime warning when the server detects a dropped key. The warning text in #17 references this README section by name; both can land in either order, but #17 reads cleaner once this doc is in place.
