Two data errors in sources.md files:
- agentskillsio/sources.md: Contributing files used agentskills-* prefix
(e.g. agentskills-overview.md) but actual filenames have no prefix
(overview.md, specification.md, etc.)
- write-agent/references/sources.md: plugin-marketplace-architecture entry
used a machine-specific absolute path; replaced with repo-relative path

Adds write-agent to plugins/kyberforge/skills/ — a factory skill parallel
to write-skill that authors Claude Code subagent definitions and cross-tool
plugin agents (Claude Code + GitHub Copilot CLI two-file pattern).
Includes research references (claude-code-agents.md, copilot-cli-agents.md,
cross-compat.md), three asset templates (subagent, plugin-agent-claude,
plugin-agent-copilot), eval coverage, and CATEGORIES.md updated to register
write-agent in the factory category per the conflict check finding.
