Why

The current lifecycle proof uses the generic development plugin, but operators need a concrete SCUM server plugin that can be discovered from the plugin marketplace and used to create multiple SCUM server instances through the platform-mediated lifecycle path.

What Changes

• Add a first-party local SCUM server plugin directory under plugins/examples/scum-server-plugin.
• Copy the existing safe plugin lifecycle pattern into SCUM-specific manifest metadata, create-form schema, plugin pages, and lifecycle action templates.
• Update plugin validation so both the development plugin and SCUM plugin are validated by default.
• Extend local debug smoke coverage so the plugin marketplace can discover the SCUM plugin and the platform can create multiple SCUM server instances from it.

Capabilities

New Capabilities

• scum-server-plugin: Provides a local SCUM game management plugin discoverable through the plugin marketplace and usable for multi-instance platform-mediated lifecycle workflows.

Impact

• Affects plugins/ example plugin assets, manifest validation, and tests.
• Affects scripts/local-debug-smoke.sh registration and API proof data.
• Does not add billing, cloud host sales, unrelated SaaS marketplace behavior, direct plugin-run transport, raw credentials, direct sockets, or raw host paths.
