Skill self-forging plugin for DeepSeek Harness

Key features

• Automatic pattern detection — same normalized first intent completed in ≥ 2 sessions triggers a forge automatically.
• forged-dsh-forge-plugin-implementation.SKILL.md — distilled from the session that designed and built dsh-forge itself.
• Manual forge — a Web client furnace panel (tool.view.cordis, key self) with a “forge current session” button and live trace statistics.
• Agent-visible forge tool — a registered forge_skill model tool lets the agent itself trigger a forge mid-task.
• Official skill format — writes SKILL.md with YAML frontmatter (name / description / whenToUse), exactly what the official filesystem skill provider scans.
