Introduce logger infrastructure and add structured logging to every layer:
alpaca.ts (buy/sell/quote/clock), momentum-indicator.ts (evaluate flow),
momentum-strategy.ts (poll loop), index.ts (startup/cycle), and trading.ts
(market timing). Replace raw console.log calls with leveled logger. Update
all tests with appropriate console spies.

Implements MomentumIndicator (samples QQQ direction) and
MomentumStrategy (buys TQQQ on up, SQQQ on down, exits at
+1% target or 1hr timeout). Wired into Bot via index.ts.
Also fixes vitest config to exclude dist/ from test discovery.
