v0.26.17

• Rename /fork to /branch (Tip 21 / 5-new-tips) - the built-in command was renamed; /fork now spawns a background subagent
• Use "40+ tips" instead of a hardcoded count in the README title and GitHub About
• Tighten the dx plugin blurb to "skills for everyday dev workflows"

Thanks to @henryiii for reporting the /fork rename (#34).
