🔀 fix: MCP Improvements, Auto-Save Drafts, Artifact Markup (#7040)

* feat: Update MCP tool creation to use lowercase provider name

* refactor: handle MCP image output edge cases where tool outputs must contain string responses

* feat: Drop 'anyOf' and 'oneOf' fields from JSON schema conversion

* feat: Transform 'oneOf' and 'anyOf' fields to Zod union in JSON schema conversion

* fix: artifactPlugin to replace textDirective with expected text, closes #7029

* fix: auto-save functionality to handle conversation transitions from pending drafts, closes #7027

* refactor: improve async handling during user disconnection process

* fix: use correct user ID variable for MCP tool calling

* fix: improve handling of pending drafts in auto-save functionality

* fix: add support for additional model names in getValueKey function

* fix: reset form values on agent deletion when no agents remain
