fix: improve reasoning summary to explicitly mention trades

The reasoning summary was not accurately reflecting actual trades.
For example, 2 sell trades were summarized as 'maintain core holdings'.

Changes:
- Updated prompt to require explicit mention of trades executed
- Added emphasis on buy/sell tool calls in formatted log
- Trades now highlighted at top of log with TRADES EXECUTED section
- Prompt instructs: state specific trades (symbols, quantities, action)

Example before: 'chose to maintain core holdings'
Example after: 'sold 1 GOOGL and 1 AMZN to reduce exposure'

This ensures reasoning field accurately describes what the AI actually did.
