Applies the same shared-field sync logic to the two marketplace.json
files that we already applied to plugin.json: name, owner.name,
description, version, and the full plugin catalog (name, source,
description per entry) must match across .claude-plugin/ and
.github/plugin/ manifests.
Fixes .github/plugin/marketplace.json to use the canonical Copilot
schema (description and version nested under metadata) rather than
a copy of Claude's top-level format. Adds owner field to both files.
Validate.sh handles the structural divergence by extracting values
from either location before comparing.

Adds every cross-compatible component between Claude Code and Copilot CLI:
skills (shared), agents (per-tool .md vs .agent.md), hooks (per-tool
paths), and .mcp.json (shared). Both plugin.json manifests now carry all
shared identity fields (name, description, author, license, keywords)
with Copilot-specific component paths only in the root manifest.
Updates validate.sh sync check to verify shared identity fields rather
than demanding content equality, since component path declarations
legitimately diverge between tools.

Adds a new skill for creating, managing, and adopting plugins across
Claude Code and GitHub Copilot CLI marketplaces. Includes three Bash
scripts (inventory, gen_manifests, validate), three reference docs
(cross-compat, claude-code, copilot-cli), a test harness with 18
passing tests, and an eval.yaml. Also adds the `marketplace` category
to CATEGORIES.md and commits the plugin marketplace architecture
research doc that informed the skill design.
