AnachronautandClaude Opus 5 be402cc9be Assembler: a string that spells an instruction is no longer assembled as one
A token is classified after its quotes have been stripped, so a string
literal reading "ADD" looked exactly like the ADD instruction and was
assembled as one. It failed with "attempting to assemble outside the
Program Segment", a message about a mistake nobody had made.

The literal and label checks were already guarded against strings and the
instruction check was not. Mnemonics match without regard to case, so
"or" and "and" were caught by this too, and those are ordinary enough
words to want in a message.

Third of its family, after a string beginning with '0' being read as a
malformed number and a string in the Program Segment being silently
discarded. All three have the same root.

AnachronautandClaude Opus 5 ca34e077ad Add sbex.h, which was never committed
The loadable program format's header has been in the working tree since
the loader was written and has never been in the repository: the gitignore
rules matched Source/Assembler as a directory, so it was silently
untracked. Anything cloning this repository could not build it, because
secondPass.c includes this file.

This is the failure the previous commit describes, having already happened
once without being noticed.

AnachronautandClaude Opus 5 51601545ae Anchor the gitignore patterns to the repository root
Without a leading slash a pattern matches at any depth, so the rules for
the three built binaries also matched directories: "Assembler" ignored
Source/Assembler. The files already in it stayed tracked, which is why
nothing had gone wrong yet, but a new source file added there would have
been silently untracked and left out of a commit.

Found by git refusing to stage a change to Source/Assembler/firstPass.c.
