Make root Ghost bundle canonical

[nahiyankhan]

🤖 Summary

• Makes the root .ghost/ directory the canonical Ghost fingerprint bundle: resources.yml, map.md, survey.json, patterns.yml, checks.yml, and optional intent.md.
• Adds ghost.resources/v1 and ghost.patterns/v1 schemas, survey composition facts, bundle lint/verify behavior, and survey patterns generation.
• Updates ghost-drift check/review/compare to consume root bundles, with composition remaining advisory and deterministic gates staying in checks.yml.
• Rewrites docs/skills/CLI manifest around resources -> map -> survey -> patterns and removes the old profile recipe surface.
• Dogfoods the new shape by checking in Ghost's own root .ghost/ package, including a source-observed survey of the docs/UI surfaces, registry components, tokens, and patterns.
• Updates ghost-fingerprint emit context-bundle to emit from the root package by default, while preserving legacy direct fingerprint emission behind --fingerprint.

Breaking change

• Removes .ghost/fingerprint/fingerprint.md as the canonical package layout. Root .ghost/ bundles are now the supported package shape.
• Adds major changesets for ghost-fingerprint and ghost-drift.

Release notes

• Adds a patch changeset for the package-aware ghost-fingerprint emit context-bundle behavior.
