v0.4.1

Patch release: internal refactoring and build hardening on top of v0.4.0.

Changed

• the stream read/write builtins (read/read_term, write-family, nl, flush_output, character/byte I/O, at_end_of_stream) moved from io.lisp into the new io-streams.lisp, defined through a shared %define-io-dual-builtin macro that derives the current-stream and explicit-stream variants from one specification; the macro validates its clause plist at macroexpansion time so a malformed definition fails the build instead of compiling a builtin that silently always fails
• %io-options and %io-read-options share one option-list parser (%io-parse-option-list) instead of two divergent copies
• query-prolog and query-prolog-first reuse the solution-mapping core of map-prolog-solutions instead of re-decoding their options through the public entry point
• deftest-table / deftest-unification expand each table spec into its own named cl-weave case, so a failing spec is reported individually

Added

• a regression test that read_term/2 rejects unsupported read options with an ISO domain error
