conformance: exclude tcl (foreign *.tcl programs vs expected annotations) — A1 worklist complete

tcl conformance.sh walks foreign lib/tcl/tests/programs/*.tcl files, reads each
first line's '# expected: VALUE' annotation, uses python3 to escape the Tcl
source into an SX helper, evaluates via (tcl-eval-string ...), and string-compares
got vs expected in bash. No SX test suites and no SX counter/dict scoreboard, so
the shared driver can't drive it (same category as lua/js/forth). Left
conformance.sh untouched; recorded the exclusion.

This completes the A1 worklist: 4 migrated onto the shared driver (common-lisp,
erlang, feed, go) and 5 excluded as foreign runners (forth, js, ocaml,
smalltalk, tcl).

   "smalltalk runs *.st via test.sh"). conformance.sh catalogs foreign
   lib/smalltalk/tests/programs/*.st programs, runs `bash lib/smalltalk/test.sh -v`, and
