chore: remove unused generate-seed.ts and generate:seed script

[pyramation]

Summary

Removes the unused generate-seed.ts codegen script from the node-type-registry package. This script generated SQL seed files for the node_type_registry table in constructive-db, but was never actually used — the table is not queried at runtime and all 55 node type definitions live in this package's TypeScript source as the single source of truth.

Changes:

• Delete src/codegen/generate-seed.ts (288 lines)
• Remove "generate:seed" script from package.json
• Remove "Codegen: SQL seed" section from README.md

No runtime code, exports, or the remaining generate:types script are affected.

Companion PR: constructive-io/constructive-db — updates docs/skills that referenced node_type_registry as the source of truth to point to this npm package instead.

Review & Testing Checklist for Human

• Verify nothing else in the monorepo imports or references generate-seed.ts (a quick grep for generate-seed or generate:seed across the workspace)
• Confirm the generate:types codegen path is unaffected (the only remaining file in src/codegen/)

Notes

• Package build (pnpm build) was verified to pass after the deletion.
• The node_type_registry table schema in constructive-db is intentionally left in place (harmless); only documentation references were updated in the companion PR.
