- brain.py: prefers direct Anthropic API (ANTHROPIC_API_KEY) over Hermes
for all LLM calls — ~22x cheaper (122 tokens vs 5600+ Hermes overhead).
Falls back to Hermes then Ollama if key unavailable.
extract_task_fields(): non-streaming call returns clean {title, project}
from any natural language phrasing — no more regex whack-a-mole.
- token_log.py: appends every LLM call to token-usage.jsonl with intent,
in/out token counts, and USD cost. get_summary() aggregates all-time,
today, and per-intent breakdowns.
- main.py: task handler uses extract_task_fields() with regex fallback;
streaming handler captures usage from final chunk; GET /usage endpoint
returns live cost summary.
