Adopt the engineering documentation standard

Adopt the engineering documentation standard Declares the repository at Component tier: a Composer plugin, so a README and agent instructions, no docs/ tree. The README keeps every word of the customising guide and gains the front matter the standard requires — status, requirements, quick start, a command table, how we work, ownership and distribution. Someone arriving cold can now install it and knows who to ask. CLAUDE.md held a description of the package, which is a fact about the code and belongs where engineers look. It is now the single pointer to AGENTS.md, and AGENTS.md carries the guardrails that were nowhere before: the .dist files are overwritten on every install, a preset change is a release because it reaches every consuming project, and hook installation is tested against a real checkout because a broken hook fails silently at commit time. Ownership is @hussainweb, the maintainer. No -admins team exists, and the standard allows a single account where no team owns the repository. Support is a GitHub issue rather than a Slack channel, because this repository is public and people outside Axelerant install the package. The workflow is copied in unmodified at enforcement: warn, which is the adoption path — it becomes block once the set is complete.
