- Implemented a unified normalization flow by switching Google/CCA handling to normalizeSchemaForGoogle/CCA. - Added normalize.ts with recursive node normalization, nullable-union checks, and combiner collapsing. - Removed sanitize-google.ts and normalize-cca.ts, replacing them with normalize exports in schema indexes. - Added spill-to-description utilities with spill/paren modes and `$defs` exclusion for unsupported fields. - Updated MCP bridge and schema tests to use normalizeSchemaFor* APIs with expanded compatibility checks. - Documented normalization behavior changes and breaking rename in constraints and package changelog files.
