docs: drop drifted GOVERNANCE.md, point README to canonical (org-ops D11)

This repo's copy had drifted from repo-standard's canonical GOVERNANCE.md
(118 vs 131 lines) and isn't required for the plugin repo class. Removed
it and repointed README.md's link to the canonical source. The
repo-specific fork guidance the local copy carried (tone-variant
suggestions, what to change first, style-feedback ask) moved into a new
README "Forking this" section so it isn't lost.

+## Forking this
+
+The most likely fork is a tone variant — a more terse style for terminal-only users, a more verbose style for non-technical readers, a different language match policy, or directives tuned to your organization's communication norms. It's one short Markdown file plus a manifest; forking is trivial.
+
+What to change first:
+
+- **Identity** — rename the plugin, replace authorship, update this README.
+- **Style content** — the directives in `output-styles/human-friendly.md` reflect the original author's taste. Adjust them to your team's voice.
+- **Frontmatter** — `name` and `description` show up in `/config`. Pick names that won't collide with other forks installed on the same machine.
+
+If a directive produces output that doesn't feel human-friendly in your context, that's useful feedback for the upstream maintainer — concrete examples beat abstract complaints.

 ## Versioning and stability
 
 - Semantic versioning. Style content changes that affect Claude's output are minor or major bumps; pure typo fixes in the README are patch.
