feat: fork drizzle-typebox as @alkdev/drizzlebox

- Rebrand package from drizzle-typebox to @alkdev/drizzlebox
- Replace @sinclair/typebox with @alkdev/typebox in all source and test files
- Replace @sinclair/typebox with @alkdev/typebox in rollup externals
- Convert tsconfig.json from monorepo extends to standalone config
- Fix build script monorepo remnant (dist.new -> dist)
- Add missing devDependencies (recast, tsx, typescript, resolve-tspaths)
- Replace monorepo link dependency for drizzle-orm with ^0.38.4
- Add .gitignore, LICENSE (Apache-2.0 with attribution), and README
- Initialize git repo with remote at git.alk.dev:alkdev/drizzlebox
