chore: remove project-wide license declarations

[builtbyrishabh]

Problem

Nexus currently grants project-wide MIT permissions, which the owner wants to stop offering for future revisions.

Solution

Remove the root license file and package license field, replace the README license declaration with Rishabh Singh’s copyright attribution, and remove the outdated license claim from launch documentation. Clarify that previously licensed copies retain their permissions and third-party components retain their own terms.

Verification

• pnpm typecheck: passed.

• pnpm test: 181 passed.

• DATABASE_URL=postgresql://user:password@localhost:5432/nexus pnpm build: passed.

• git diff --check: passed.

• Verified no remaining project license file, package declaration, or license badge.

• I kept this change focused and updated related documentation.

• No runtime behavior changed; no new tests were needed.

• I did not include secrets, credentials, or private user data.

Summary by CodeRabbit

• Licensing
  • This revision no longer includes a project-wide license. Copies licensed under earlier versions retain their original permissions, and third-party components remain subject to their own licenses. The README and package metadata have been updated to reflect this change.
