MCP server v2.24.0: Document patching and schema deployment fixes

Improvements

patch_documents tool: Renamed from patch_document and added support for applying patches to multiple documents in one call.

patch_documents tool: Reworked patching to mirror @sanity/client patch() operations. It now accepts an array of patches built from set, setIfMissing, unset, inc, dec, insert, and diffMatchPatch plus append and prepend shorthands, with an optional ifRevisionId guard. All patches in a single call are applied as one transaction. Edits continue to save to the draft or release version, and editing documents in a release is supported with releaseId.

create_version tool: Uses the draft content as the base for new release versions when a draft exists.

Fixes

deploy_schema tool: Fixed an issue where deploy_schema could fail with a duplicate media field error after deploying image or file types, which blocked further schema changes for some users. Affected schemas recover automatically on the next deploy.
