Michał Pierzchała 5a362ec752 build: drop tsc entirely and fix sandbox-hostile tests (#1100)
Follow-ups from the bundler/CI speed work, re-validated against latest
main. The typescript package is gone from the toolchain:

- pnpm typecheck stays on tsgo; the typecheck:tsc escape hatch is
  removed along with the typescript devDependency.
- args.test.ts extracted cli.ts dispatch literals through the
  TypeScript compiler API - the only remaining consumer. It now walks
  the same AST via oxc-parser (matching the OXC lint/format/build
  stack); both implementations extract an identical 14-literal set
  from cli.ts, verified side by side before the swap. The
  substitution-free template case ts.isStringLiteralLike covered is
  preserved.
- dts bundling is unaffected: the tsdown build uses the tsgo backend
  and builds green with no typescript package installed.

Test fixes for containerized agent environments:

- The missing-binary doctor-guidance web provider test pins Node 24
  via the file's existing withNodeRuntimeVersion helper, so it asserts
  the setup hint instead of inheriting the host Node and failing on
  Node 22 (the supported engines floor).
- The clean-xcuitest cleanup-failure smoke test skips as root: chmod
  0o500 cannot force a removal failure when the process bypasses
  directory permissions.

AGENTS.md toolchain notes updated to match.
