exchange-insights: add plugin

[TheSpryt]

Adds Exchange Insights — live Grand Exchange market data inside the native GE interface.

What it does (zero setup, works anonymously):

• Replaces the examine text in the GE offer setup/details with live market data: insta-buy / insta-sell, item margin, buy limit and actively-traded price
• Offer-age badges on GE slots, and slot outlines/labels showing how far an offer is behind the market ("Sell -14,774 at market")
• Optional left-click Collect to bank

Optional account link (off by default, one-click browser approval):

• Syncs your GE offer book to your own Exchange Insights dashboard for verified flip tracking (buy→sell round-trips) and opt-in "offer behind market" alerts delivered as chat messages / RuneLite notifications

Review notes:

• All network I/O is HTTPS to a single user-configurable endpoint (default https://exchange-insights.gg); token is a per-user secret stored via ConfigManager (secret = true); no third-party telemetry
• Read-only display + data sync — no gameplay automation, no reflection, standard RuneLite APIs (widgets, sprite override, Notifier, ConfigManager, @schedule)
• BSD 2-Clause, icon 48×48
