fix(core): silent ABORT, and name the compile-only condition

Two reporting bugs found from the browser shell.

An uncaught ABORT printed 'ABORT (throw -1)'. The standard defines ABORT
as 'empty the data stack and perform the function of QUIT', and QUIT
displays no message; gforth and SwiftForth are both silent. It now takes
the same silent path QUIT got in 0.2.5. CATCH still reports -1 and still
restores the stack depth, and ABORT" still prints its text -- different
word, different code (-2).

Compile-only constructs used in interpretation state claimed to be an
'unknown word', which is misleading for a word the system obviously
knows: ABORT", IF, THEN, LOOP, LITERAL, RECURSE and friends. They now
report 'interpreting a compile-only word: <name> (throw -14)', the
standard condition both reference engines give. The check reuses the
existing INTERPRETER_TOKENS table at the point where interpretation has
already failed, so a genuine typo still reports 'unknown word'.

Ships as v0.2.6.
