docs(language): document exception handling and runtime behavior

Add the TRY manual for CATCH, ENDTRY, and anonymous THROW. Update runtime
error descriptions, language links, and native linking examples; document
catch cleanup and embedded runtime integration in the architecture notes.

Verify manual generation, rendered output, relative links, and the TRY
example. Record Linux LLVM 18 validation and unverified Windows/macOS support.
