chore: Upgrade to TypeScript 7.0

Bump typescript to ~7.0.2 and apply the changes TS 7 requires:
- remove downlevelIteration and baseUrl (both removed in TS 7)
- set explicit rootDir on all emitting tsconfigs (now required)
- add DOM lib and node types to the shared base config
- scope DOM out of cloudflare (conflicts with workers-types)
- source fixes: BodyInit casts on transports, readonly web-vitals
  globals, WebAssembly.Exception ts-expect-error removal, elysia
  trace handler generic, replay paint entry ts-expect-error
