Add canvas-plugin Gradle plugin module

[Copilot]

Adds a new dev.slne.surf.surfapi.gradle.canvas-plugin Gradle plugin for Canvas server targets, inheriting all paper-plugin behaviour (plugin.yml generation, runServer, surf-api wiring) while substituting canvas-api as the compile target and resolving the org.bukkit:bukkit capability conflict in favour of Canvas.

Changes

• AbstractPaperPluginSurfPlugin<E> — extracted paper-plugin logic from PaperPluginSurfPlugin into a generic abstract base; PaperPluginSurfPlugin now delegates to it unchanged
• CanvasSurfExtension — extends PaperPluginSurfExtension, inheriting all existing DSL methods; defaults foliaSupported to true (can be overridden explicitly)
• CanvasPluginSurfPlugin — extends AbstractPaperPluginSurfPlugin<CanvasSurfExtension>; overrides applyRepositories0() to add the Canvas Maven snapshot repo and configure0() to add canvas-api + capability resolution
• canvasMaven() — new RepositoryHandler extension in repo-extensions.kt, mirrors the existing slnePublic() pattern
• libs.versions.toml / Constants.kt — canvas-api version managed via version catalog and exposed as Constants.CANVAS_API
• build.gradle.kts — registers dev.slne.surf.surfapi.gradle.canvas-plugin

Usage

plugins {
    id("dev.slne.surf.surfapi.gradle.canvas-plugin")
}

surfCanvasPluginApi {
    mainClass("com.example.MyPlugin")
    bootstrapper("com.example.MyBootstrap")
    authors.add("yourname")
}

Canvas plugins have foliaSupported enabled by default. The capability resolution ensures canvas-api wins when transitive dependencies pull in paper-api or plain bukkit:

configurations.all {
    resolutionStrategy.capabilitiesResolution.withCapability("org.bukkit:bukkit") {
        select(Constants.CANVAS_API)
    }
}

CanvasSurfExtension now overrides the foliaSupported convention to true in its init block, so every canvas plugin has Folia support enabled by default (can still be overridden explicitly). Done in 1c7e8af.

Pull request overview

Adds first-class Gradle plugin support for Canvas server targets within the existing surf-api-gradle-plugin module, reusing the Paper plugin implementation while swapping the compile target to canvas-api and handling org.bukkit:bukkit capability conflicts.

Changes:

• Extracted shared Paper plugin behavior into AbstractPaperPluginSurfPlugin and made PaperPluginSurfPlugin delegate to it.
• Introduced canvas-plugin Gradle plugin + DSL extension with foliaSupported = true by default.
• Added Canvas repository helper + version-catalog/Constants wiring for canvas-api.
