chore(repo): add MIT license file to root and all published packages

[designcode]

Every package.json declares "license": "MIT", but the repo had no license text — GitHub reported license: null, and published tarballs shipped the metadata without the notice (@tigrisdata/cli@3.7.0 on npm has no LICENSE).

Adds the MIT text at the repo root and in each of the eight published packages. Per-package because npm publishes package directories, not the repo, so a root-only file never reaches consumers. No manifest changes needed — npm includes LICENSE regardless of the files array.

Test plan

• pnpm test in packages/cli — 834 passed, 214 skipped
• biome check clean
• pnpm pack on @tigrisdata/cli includes package/LICENSE
