Add comprehensive Xcode file type UTIs

Expand FILE_TYPES_BY_EXTENSION with many additional file extensions and their Xcode UTIs (derived from Xcode built-in file type specs) and add a much larger FileType union in src/json/types.ts. Also include documentation comments and an escape-hatch type (string & {}) for unknown UTIs. A few existing mappings were adjusted to better match Xcode conventions (e.g., bundle, markdown, mdimporter). These changes improve extension handling and align project types with Xcode specs.
