dsh-plugin-lol-mayhem: A Hextech Mayhem query plugin for DSH agents integrated with QQ bots

A native Host plugin for DSH, maintained by NormalAorii, targeting agents connected to the official QQ bot. It registers 13 `lol_*` tools: comprehensive hero guides and Top 6 Hextech Augments (including mechanism explanations and win/pick rates), Hextech Augment rankings and archives, three-item build sets by archetype, three-Augment combinations, hero comparisons, tier lists, trending dark horses, fuzzy search, data versioning and online refresh, and generating 1080px-wide PNG image cards via `qqbot_send_file` to send to groups. Data is sourced from the aramgg official client public API (173 heroes, 218 Augments, 306 items), including offline snapshots and maintenance commands `npm run crawl` and `npm run verify`. op.gg does not provide hero-level Hextech Augment statistics; this is a known limitation that `lol_meta` will document. Installation is via `plugin_manager install_bundle`, offline `.tgz` files, or manual `cordis.patch.yml`, requiring the host to have the tools service enabled. Image generation requires Windows PowerShell with System.Drawing. Licensed under the MIT license, with data copyright held by aramgg and Riot Games.
