v1.0.0

Release notes:

• PRINT shorthand: ? now highlights like PRINT.
• DATA safety: Lines without commas/quotes treat the rest as plain text, so keywords/numbers inside unquoted payloads don’t get highlighted.
• Single-line strings: Unclosed quotes stop at EOL; no bleed to the next line.
• Multi-word keywords fixed: SET/LOAD/SAVE variants (e.g., SET FNKEY, LOAD COLORMAP, SAVE SCREEN) now highlight fully.
• Color consistency: OFF matches ON (bright blue); numeric literals in light magenta.
• Keyword coverage: Added list tokens (ATTRLIST, PALETTELIST, RGBLIST, TILELIST) and joystick helpers (JOYx family).
