chore: build and type-check with the native TypeScript 7 compiler

Clean builds drop from ~3.7s to ~0.7s (~5x) with byte-identical emitted
JavaScript.

TypeScript 7 ships only the native binary, without the JS compiler API
that ts-jest, ts-node and typescript-eslint require (none support 7 yet),
so the compilers are split:

- typescript@^5.9.3 remains the "typescript" package for ts-jest,
  ts-node and ESLint
- typescript-go (npm alias of typescript@^7.0.2) drives the build and
  type-check scripts, invoked by explicit path since both packages
  declare a tsc bin

Config migrations required by TS 7:

- tsconfig.json: explicit rootDir; removed moduleResolution node10
  (deleted in TS 7, the new default resolves identically here)
- test/tsconfig.json: pin strict:false, TS 7 flips the default to true
  which surfaces 344 pre-existing test typing errors
