agent: ensure today's daily note file exists before LLM read_file

Browse source 
- Add EnsureTodayFile() to create memory/YYYYMM/YYYYMMDD.md with date header if missing
- Call it from GetMemoryContext() so path advertised in system prompt always exists
- Avoids read_file tool failure when agent (or cron) tries to read today's note
