Parse hyphenated quoted symbols

[theaspirational]

Summary

• Allow - in tick-quoted symbol literals.
• Cover hyphenated quoted symbols in parser branch coverage.
• Remove a stale test comment saying hyphenated symbols parse as operators.

Why

The language docs describe quoted symbols as supporting alphanumeric names plus hyphens, and bare names/keyword literals already accept hyphenated forms. Before this change, 'a-b parsed as 'a followed by unresolved -b, so documented symbols failed to parse as a single literal.

Validation

• make test TEST_CORES=2
