Resolve conflicts against main:
- Inventory moved to src/artifacts/inventory (#1032); point the xar and
cpio reader imports at their new relative paths.
- README.md: take main's simplified English README, which no longer
lists individual package formats. PKG coverage stays documented in
the skill reference and docs/testing.md.
- Skill: the references gain the PKG paragraph, so the version moves to
29 (main already uses 28).
- Regenerate the product catalog, conformance manifest, skill digest and
package metadata. The MCP tool catalog is now built rather than
committed (#997), so it is removed here.
