Add Grand Flip Out plugin by Tunatroll

[Tunatroll]

Grand Flip Out is a comprehensive Grand Exchange flipping companion for OSRS.

What it does:

• SmartAdvisor intelligence engine: combines JTI scoring, RSI/EMA/MACD technical analysis, bot economy tracking, dump detection, and data quality scoring into a single 0-100 composite score per item with a clear BUY/HOLD/SELL/AVOID recommendation
• Auto-tracks completed GE transactions via the RuneLite event API (GrandExchangeOfferChanged)
• Detects price dumps and classifies by type (coordinated dump, panic sell, supply flood, ban wave)
• Tracks bot-farmed item supply pipeline and ban wave signals
• Multi-account portfolio tracking (information only)
• In-game overlay showing margin, volume, and SmartAdvisor score
• Configurable flip suggestions sorted by margin %, ROI, or profit per GE limit

Compliance:

• Information only - does NOT automate any GE interactions
• No game packets sent or intercepted
• No memory read beyond the RuneLite Client API
• All HTTP calls use RuneLite injected OkHttpClient
• Calls OSRS Wiki Prices API and RuneLite Prices API (rate-limit-respectful, 60s+ refresh)
• No third-party implementation dependencies
