dsh-godot-workflow: A Local Plugin for Godot Project Development Workflow

DSH's `AGENTS.md` has a 65536-byte limit, causing resident workflow rules to be easily discarded and rendered ineffective. The `dsh-godot-workflow` plugin, developed by AtlacherCoder, splits the Godot workflow into two parts: a lean resident core that does not count against the budget, and full skills loaded on demand. The plugin includes five strict rules, a workflow skeleton, and detailed specifications, and is installed via the `link:` protocol, but modifying its source code requires restarting `dsh web`. It also includes a self-check script to ensure the workflow remains available when the budget is tight.
