feat: replace inject_ai_prompt with custom_ai_prompt_text (#151)

Replace the boolean `inject_ai_prompt` with an optional string
`custom_ai_prompt_text` so users can define their own prompt text.
Add panic() when the old field is detected to prevent silent breakage;
will be fully deprecated in v4.0.
