chore(context): drop cursor + aider adapters from generator

Cursor and Aider are not supported harnesses. Remove generate_cursor
and generate_aider, their no-arg calls, and their case arms. The active
adapters are claude (CLAUDE.md), agents (AGENTS.md), and system-prompt
(.context/system-prompt.txt).
