feat(fundamental): add fundamental analysis suite (growth, valuation, risk, compare)

- Add Fundamentals type and MarketDataProvider::fundamentals() trait method
- Add Yahoo quoteSummary endpoint parser (/v10/finance/quoteSummary)
- Add analysis/fundamental.rs with exact signal thresholds ported from idx-mcp:
  - GrowthReport (revenue/earnings growth with signals)
  - ValuationReport (PE, PB, ROE, margin, EV/EBITDA with signals)
  - RiskReport (D/E, current ratio, ROA with signals)
  - FundamentalReport (composite with overall health signal)
- Wire CLI subcommands: stocks growth/valuation/risk/fundamental/compare
- Add table + JSON rendering for all report types
- Add mock fixture (quotesummary_bbca.json)
- 41 tests passing (22 unit + 19 integration)
- Known: Yahoo quoteSummary returns 401 from datacenter IPs (needs crumb auth)
