feat: complete Faza 1 implementation (105 tests green)

All 12 modules built per reviewed plan:
- detector, state_machine (5-state phased FSM), canary, levels Phase B
- notifier fanout (Discord + Telegram, bounded queue, retry, dead-letter)
- audit (JSONL daily rotation), journal, report (weekly R-multiple PnL)
- calibrate + labeler (Tk, lazy-imported), dryrun with acceptance gate
- unified CLI: atm calibrate|label|dryrun|run|journal|report

README + Phase 2 prop-firm TOS audit checklist included.
