feat: add 19 fast commands (no-LLM) + incremental embeddings indexing

Fast commands for git, email, calendar, notes, search, reminders, and
diagnostics — all execute instantly without Claude CLI. Incremental
embeddings indexing in heartbeat (1h cooldown) + inline indexing after
/note, /jurnal, /email save. Fix Ollama URL (localhost → 10.0.20.161),
fix email_process.py KB path (kb/ → memory/kb/).
