Add sap- namespace alongside existing SAP entries

Adds 5 sap-prefixed plugin entries (sap-cds-mcp, sap-fiori-mcp-server,
sap-hana-cli, sap-ui5, sap-ui5-typescript-conversion) without removing
the existing cds-mcp, ui5, and ui5-typescript-conversion entries. This
is an additive, non-breaking change — existing installs continue to
resolve unchanged while new users can adopt the sap- namespace via
SAP's documentation.
